RGB color value is specified with RGB(red, green, blue).
Each parameter of the RGB (red, green, and blue) values defines the intensity of the color as an integer between 0 and 255. For example, RGB (0, 0, 255) is rendered as blue, because the blue parameter is set to its highest value (255) and the others are set to 0. (0, 0, 0) is black, and (255, 255, 255) is white.
Hexadecimal color value
is specified with hexadecimal values between 00 (zero zero) and ff, specifying the intensity of the color. For example, #0000ff is displayed as blue, because the blue component is set to its highest value (ff) and the others are set to 00.Hexadecimal color values increase by this fashion, until reaching 9f, then a0:
(example):
00, 01, 02, 03, 04, 05, 06, 07, 09, 0a, 0b, 0c, 0d, 0e, 0f, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 1a, 1b, 1c, 1d, 1e, 1f, 20, continuing to 9f. Next,
a0, a1, a2, a3, a4, a5, a6, a7, a8, a9, aa, ab, ac, ad, ae, af, b0...and so on, continuing to ff.
HSL color values are specified with: (Hue, Saturation, Lightness).
-
Hue is a degree of color from 0 to 360. 0 is red, 120 is green, 240 is blue, 300 is fuchsia(magenta), and increases to 360 as the color returns to red.
-
Saturation is the amount of grey that is added. Saturation is a percentage value; 0% means the color will be grey, 100% means no grey is added, the hue is it's full color.
-
Lightness is a percentage value of the amount of black and white that will be added to the color. 0% means all black, and 100% means all white. Setting the lightness to 50% is your original hue color.
