I'm checking equation for the layer mode. I know white is 255, and black is 0. These values are useful for calculation for layer equations like multiply and divide.

How do I know color values? Do you know color values for major colors?

White is RGB 255,255,255
Black is RGB 0,0,0
Colour values are something like RGB 50,100,150

Inside the change colour dialogue, you can choose between a 0-100 or a 0-255 range.

Sample the color with the color picker (this copies the color to the Foreground color) then use the color selector, that will display the valie for the FG/BG colors.
