value
(Or "tone", "luminance", "value", "luminosity",
"lightness") The coordinate in the HSB colour model that
determines the total amount of light in the colour. Zero
brightness is black and 100% is white, intermediate values are
"light" or "dark" colours.
The other coordinates are hue and saturation.

HSB
(HSB) A colour model that describes colours in
terms of hue, saturation, and brightness.
In the tables below, a hue is a "pure" colour, i.e. one with
no black or white in it. A shade is a "dark" colour, i.e. one
produced by mixing a hue with black. A tint is a "light"
colour, i.e. one produced by mixing a hue with white. A tone
is a colour produced by mixing a hue with a shade of grey.
Microsoft Windows colour dialogs, PagePlus, and {Paint
Shop Pro} use HSB but call the third dimension "luminosity"
or "lightness". It ranges from 0% (black) to 100% (white). A
pure hue is 50% luminosity, 100% saturation.
Colour type S L
Black Any 0%
White Any 100%
Grey 0% 1-99%
Hue 100% 50%
Shade 100% 1-49%
Tint 100% 51-99%
Tone 1-99% 1-99%
Quattro Pro, CorelDraw, and PhotoShop use a variant
(Quattro Pro calls the third parameter "brightness") in which
a brightness of 100% can produce white, a pure hue, or
anything in between, depending on the saturation.
Colour type S B
Black Any 0%
White 0% 100%
Grey 0% 1-99%
Hue 100% 100%
Shade 100% 1-99%
Tint 1-99% 100%
Tone 1-99% 1-99%
[Same as HSV?]
