Specifying Colors

Max specifies color with either four floating-point numbers between 0 and 1, or a Dynamic color name.
For the four floating-point numbers, the first three numbers are for the R, G, and B components, and the fourth value is for alpha. We call this format RGBA. Alpha defines the transparency of the color. If the alpha is 0, you won't see the color at all. If the alpha is 1, the color is completely opaque. When converting between a legacy color style, the alpha is set to 1.
The Dynamic color name references a specific color that corresponds to a graphical element in the Max or Live user interface.
