Red, Green, Blue
“This color model is based on adding and mixing light – when you add Red, Green, and Blue light together, you create a pure white.” Modern Soapmaking, DIY Design: What’s the difference between RGB and CMYK?. Think of aiming spotlights onto a dark stage.
R0 B0 G0 = C0 M0 Y0 K100 = hex 000000 = black
s = R255 G0 B0 = C0 M100 Y100 K0 = hex ff0000 = red
0 = R0 G255 B0 = C100 M0 Y100 K0 = hex 00ff00 = lime green
t = R0 G0 B255 = C100 M100 Y0 K0 = hex 0000ff = blue
b = R255 G255 B255 = C0 M0 Y0 K0 = hex ffffff = white
Cyan, Magenta, Yellow, Black
“In subtractive color theory, all colors mix to yield black.” Color Matters, Color Systems – RGB & CMYK . CMYK is used for printing. Art media is also subtractive. Think of colored paints piled on a white canvas
C0 M0 Y0 K0 = R255 B255 G255 = hex ffffff = white
s background = C100 M0 Y0 K0 = R0 B255 G255 = hex 00ffff = light blue, i.e. cyan
o background = C0 M100 Y0 K0 = R255 B0 G255 = hex ff00ff = hot pink, i.e. magenta (In my mind, magenta is darker than this.)
t background = C0 M0 Y100 K0 = R255 B255 G0 = hex ffff00 = yellow
b background = C0 M0 Y0 K100 = R0 B0 G0 = hex 000000 = black (also = C? M? Y? K100, as far as I can tell)
So it seems that a single RBG color is equal to two CRMK colors. Vice versa, a single CRMK color is equal to two RBG colors. Would you like to convert the CMYK color to a RGB model? This page gives conversion formulas & an automatic converter with handy sliders.

Anyone who understands color theory want to educate/correct me? I’m leaving HSL for another day.
