Color Mixer

Mix a color from red, green and blue parts and calculate the color value. Each color can have a value from 0 to 255 (decimal) and from 00 to ff (hexadecimal). The color can be adjusted using the sliders or entered as numerical values.

Red:

Green:

Blue:

The hexadecimal color value following the # symbol represents the complete color value, which can be used directly for image editing and color coding. The default setting for this color calculator is medium gray, #808080, one of the two mid-range values in the RGB color space. The corresponding button returns the display to this setting.

Screen colors are composed of three components: red, green, and blue. The baseline value is black, #000000. Adding any amount of one or more colors increases the brightness, reaching a maximum at white, #ffffff. The first two digits indicate the red component, the next two the green component, and the final two the blue component. Each component can have 256 levels, ranging from 0 to 255, or 00 to ff in hexadecimal, resulting in 256³=16,777,216 possible color combinations. Hexadecimal notation is typically chosen here to yield six-digit color codes rather than nine-digit ones.
In this context, green serves as a primary color, unlike yellow, which is a primary color for opaque pigments, because yellow is inherently brighter than red and blue and is created by combining red and green. With opaque pigments, by contrast, adding a color does not automatically increase the overall brightness.
If all three color values are equal, the color is a shade of gray. Three similar values result in low color saturation. The further apart the values are, the higher the saturation. Perceived brightness is influenced most strongly by the green component, followed by the red component, and least by the blue component. This is because green lies in the middle of the visible spectrum and is therefore most easily perceived by the human eye. For more information on this topic, please refer to the gray tone calculator.
