The other channels are the colors mixed with the key color, and the color of each channel is determined by the amount of the key color mixed in. At least one of the channels is black, and the color of this channel is known as the key color. The CMYK color space is a subtractive color space, in which the color of each channel is created by subtracting the color of one channel from the remaining channels. It is a color space composed of four channels, where each channel is represented by 8 bits. In addition to the RGB and RGBA color spaces, there are other color spaces that are widely used in programming:ĬMYK: The CMYK color space is the color space that is used for printing. This means that if the alpha channel has a value of 255 (opaque), it does not represent a transparent pixel. In addition, the alpha channel can be accessed in order to make an image transparent.
The RGBA color space is used to calculate the color of each pixel that can be displayed on the screen. Equal values of each channel are represented by the same color in the RGBA color space, but the combination of different values of each channel leads to different colors. Also, if the value of each channel is set to 0, the color of the visualized color space results in black. For example, if the value of each channel is set to 255, the color of the visualized color space results in white. In the RGBA color space, the alpha channel is considered the same as a fourth channel, and the light intensity of each channel is equal to the value of each channel. This means that the alpha channel is composed of 256 levels of transparency, where 0 represents the maximum level of transparency, and 255 represents the maximum level of opacity. The alpha channel can be displayed as a grayscale image. In RGBA, the transparency information is stored in the alpha channel, and the color information is stored in the three RGB channels. An RGBA color is composed of four channels, where each channel is represented by 8 bits. The RGBA color space is a color space that includes an extra channel (alpha channel) for representing the transparency information of an image.
The RGB color space is used to calculate the color of each pixel that can be displayed on the screen. Also, if the value of each channel is set to 0, the color of the visualized color space results in black.Įqual values of each channel are represented by the same color in the RGB color space, but the combination of different values of each channel leads to different colors. In the RGB color space, the light intensity of each channel is equal to the value of each channel. The components of RGB are represented by the mathematical model: R = red (0 ≤ R ≤ 255) The RGB color space is a combination of the red, green, and blue light components of additive color. Each channel is represented by 8 bits, and the value of each channel is a value from 0 to 255. An RGB color space is a color space composed of three channels: red, green, blue, representing the three-dimensional information about the color. A color space is a mathematical model used to represent physical colors.
