See it as a painters color palette, with the numbers you determine how many of the color you use.
(0, 0, 0) r, g, and b on 0 gives black, #000000 in hexadecimal
(255, 255, 255) all on 255 gives white, #FFFFFF in hexadecimal
(255, 0, 0) g and b on 0 and r on 255 gives red, #FF0000 in hexadecimal
(0, 255, 0) r and b on 0 and g on 255 gives green, #00FF00 in hexadecimal
