A very basic color tool for adjusting hue, saturation, lightness and alpha of a given RGB color.

Usage:

var col = new Qolor('#ffcc00');
col.H = 120; // hue, 0..360
col.S = 0.5; // saturation, 0..1
col.L = 0.5; // lightness, 0..1
col.A = 0.5; // alpha, 0..1

Parameter for new Qolor(...) can be in any of these:

• #0099ffAA
• #09fA
• #0099ff
• #09f
• rgb(64, 128, 255)
• rgba(64, 128, 255, 0.5)

Note: if you pass hex values to it, toString() will return hex values too. If you do rgba(), it'll return rgba() accordingly.
