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. To pick RGB/RGBA/Hex/HSL colors from an image (without uploading it to any server), check out our Image Color Picker. To pick RGB 0-1 colors, check out our RGB 0-1 Color Picker. RGB 0-1 or Float RGB is another alternative representation of RGB colors that uses three decimal numbers between 0 and 1 to represent the color: one each for red, green, and blue, and one for an optional alpha channel. To pick RGB 565 colors, check out our RGB 565 Color Picker. This color space is used in some embedded systems, such as microcontrollers. RGB 565 is an alternative representation of RGB colors that uses 16 bits to represent the color: 5 bits for red, 6 bits for green, and 5 bits for blue. 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. For example, if the value of each channel is set to 255, the color of the visualized color space results in white. 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. As using the mouse to extract a color can be inaccurate, to avoid losing the exact point where you want to extract the color, you can use the precise Cartesian (x, y) coordinate options, which lock the location of the pixel.A color space is a mathematical model used to represent physical colors. The increased radius is shown with a green border in the magnifying glass and also on the JPG itself. Similarly, an eyedropper of radius 3 extracts an average color from an area of 5×5 (it's the center pixel plus two pixels to all sides). For example, an eyedropper of radius 2 extracts the average color from an area of 3×3 (it's the center pixel, plus another pixel in all directions). If you want to get the color of a larger area than a single pixel, you can increase the eyedropper radius. This is the pixel that is used for picking the color. When you do that, a magnifying glass appears and in its center, you'll see a magnified pixel with a red border around it. To extract a color as accurately as possible, click on the loaded photo and hold down the mouse button. If necessary, you can also print any of these color codes on the output JPG by using the print-color-name option. Also, in the options below, the names of the color are printed in many, many different formats – you get the web-safe color name as text and then programmatic color codes in HEX, RGB, RGBA, HSL, HSV, HSI, LAB, LCH, and HCL formats. The color itself is painted in the output area and can be downloaded as a separate JPG. You can upload a JPG photo, click on any point on the photo with the mouse, and you'll instantly get detailed information about the selected color. With this online utility, you can extract color from JPG/JPEG and JPEG2000 pictures.
