Please tell me a few terms for the color selection box and what are the technical terms for color

First of all, all three tools are called "color pickers", but they are located in different environments.

In the upper left corner, there is the default color picker that comes with Windows, and generally software that does not have a dedicated color picker will call this color picker.

In the lower left corner, there is a dedicated color picker that comes with flash.

On the right, there is a dedicated color picker built into Photoshop.

As for things like b9b8b8, the term is called "hexadecimal color value", you can enter this value in the bottom right corner of the Photoshop color picker, and then look at the corresponding color, one color corresponds to a unique color value, when you enter this value, the rest of the parameters in the Photoshop color picker will change synchronously, and you can view the RGB color value.

Added: About hex color values When you open the Photoshop color picker you can see that there is a text box in the color picker with a " in front of it, which is entered right here.

The RGB color mode uses the RGB model to assign an intensity value in the range of 0 255 to the RGB component of each pixel in the image. RGB images use only three colors, so you can mix them in different proportions to reproduce 16777216 colors on the screen. In RGB mode, values from 0 (black) to 255 (white) can be used for each RGB component.

For example, bright red uses an r-value of 255, a g-value of 0, and a b-value of 0. When all three component values are equal, a shade of gray is produced. When the value of all ingredients is 255, the result is pure white; When the value is 0, the result is pure black.

blue represents the blue component, green represents the green component, and red represents the red component. In each component, the smaller the value, the lower the brightness, and the larger the value, the higher the brightness.

RGB format.

The methods by which a color is encoded are collectively referred to as "color spaces" or "color gamuts." In the simplest terms, a "color space" of any color in the world can be defined as a fixed number or variable. RGB (red, green, blue) is just one of the many color spaces.

With this encoding, each color can be represented by three variables – red, green, and the intensity of blue. When it comes to recording and displaying color images, R GB is the most common solution. However, it lacks good compatibility with earlier black-and-white display systems.

Therefore, it is a common practice for manufacturers of electronic and electrical appliances to convert RGB to YUV color space to maintain compatibility, and then switch back to RGB format as needed to display color graphics on computer monitors. Since the web is developed based on computer browsers, the colors are mainly optical colors RGB (red, green, blue). The colors of the web page are expressed in hexadecimal**, and the general format is defabc (letters range from a-f, numbers from 0-9); If black, it is in the web page**

000000 (abbreviated as 000 in CSS). When the color ** is aabb11, it can be abbreviated as ab1, for example, 135 and 113355 represent the same color.

Introduction to the format. RGB1, RGB4, and RGB8 are all RGB formats for palette types, and describing the details of these types of formats is usually followed by a palette (defining a range of colors) after the BitMapInfoHeader data structure. Their image data is not a true color value, but rather an index of the current pixel color value in the color palette.

If you take RGB1 (2-color bitmap) as an example, if the two color values defined in its palette are 0x000000 (black) and 0xffffff (white) in order, then the image data 001101010111....(Each pixel is represented by 1 bit) indicates that the color of each pixel is: black, black, white, black, white, black, white, black, white, white, black, white, white, black, white, black, white

The RGB values corresponding to B9B8B8 are: R185 G184 G184 and are gray.

The largest selection box on the right is: Color Picker.

The base color is the color on a person's natural hair.

Natural hair is divided into 10 base colors: 1:0 black, 2:0 black, 3:0 black, and so on.

0:00 is pure white without color.

The steps are all set.

Enter the text, which is white, to get the text layer.

Get the bottom layer 1 turquoise that selection and build one"Solid color"The adjustment layer, which is the turquoise color of the bottom plate, will result in a color-filled adjustment layer, as shown in the image above.

Set this color-filled adjustment layer to a clipping mask onto the font layer (i.e., the little clipper on the left side of the color-fill layer).

The advantage of the above steps is that you can change the color of the word at any time.

All text is set to blue on the right.

Duplicate the blue background layer to the top of the text, and add a color to the layer to overlay it as white.

Ctrl+Alt+G to create a clipping mask, successful.

After typing the font, use the color selection method to select the font, then subtract the font you don't want to fill from the selection, and choose your favorite color to fill it! Do whatever you want!

On the font layer, after rasterization, select the area to change the fill color.

It's as simple as using the selection to change the color of each section.

Long-short balance is the balance between the buyer's market and the seller's market, that is, the amount of buying is the same as the amount of selling Short cover is to sell and buy back again Short stop loss is to buy assets when ** drops to a certain extent to prevent losses from continuing to expand

If you make a profit and don't sell it, you will lose it again——— you will take profits.

**After falling for two days, you see that it is going to rise, and you buy ——— short cover.

CDP: contrarian operating system.

The market advocates chasing up and down, rather than participating in consolidation. In fact, moderate participation in consolidation can find a sense in the market, especially in the low indices away from the high-volume area. Therefore, it is imperative to seek practical skills with a better chance of winning in the handicap.

When the volume is extremely low, patience is the best policy; When there is a moderate change in volume, you may wish to follow the CDP

Design resistance and support levels to reduce costs by selling high and buying low. CDP, or "contrarian operating system", is a stock price limit based on changes in the momentum field, and it is calculated as follows:

cdp＝（h＋l＋2c）／4

h: the previous day's most**; l: the lowest price of the previous day; c: The previous day's closing price.

AH (most**) CDP (H—L).

NH (near**) CDP 2—L

al (the lowest price) cdp—(h—l).

NH (near-low price) CDP 2—H

The significance of CDP is to predict the next day's point, which is a way of fighting an imaginary enemy, and the key to judging is to look at the five values of CDP (AH, NH, CDP, NL, AL) of the stock index (stock price). In this way, investors can avoid buying at the highest price in the market and selling at the lowest price with reference to CDP.

Dude......Whether it is CG or design, it is necessary to master photography. The following explanation:

1. ISO is actually a unit of measurement for the first degree of film, and it is an international standard unit. He represents how sensitive the film is to light. Now in the digital age, it is still possible to achieve the same effect by applying different energies to the sensor.

The higher the ISO, the smaller the amount of light required to achieve the same level, i.e., the more suitable it is for use in a low environment. However, as the ISO increases, the grain of the film becomes coarse, causing so-called "noise", which is still a serious problem in the digital age, but the cause is that the electrical interference of the sensor in a high-ISO environment causes errors**.

2. Aperture. Aperture is the amount of light transmitted by the lens The larger the aperture, the more light passes through the lens per unit of time.

Aperture affects depth of field, and the larger the aperture, the smaller the depth of field. Of course, if you want to do this in 3DS, you'll have to turn on the renderer's depth of field option.

3. Shutter speed.

It is the length of time the shutter is open. The aperture represents the ability to pass light, multiplied by the shutter speed, is the total amount of light, and what kind of brightness this total amount of light can show on the film depends on the sensitivity, these three parameters are this relationship.

The higher the shutter speed, the easier it is to present a static effect, while the low shutter speed has traces of object movement, which is full of movement, but the problem brought by the low shutter speed is that it is easy to be affected by the vibration of the hand, so it is often necessary to use a tripod to shoot still life in dark conditions.

As for film speed, it is actually the sensitivity of the film.
