From Spherical
Returns a Color object that is the blended color of the two input colors, (c1 and c2) but allows you to specify the amount of each color.
Contents
Usage
Color BlendColorsWeighted(c1, c2, c1_weight, c2_weight);
- c1 Color. a color object created with CreateColor
- c2 Color. a color object created with CreateColor
- c1_weight integer. amount of first color
- c2_weight integer. amount of second color
Notes
The weights of the two colors are converted to a ratio out of 100%. (1:2 means one part of the first to two parts of the second. Or 33% of the first to 66% of the second.)
Examples
var Red = CreateColor(255, 0, 0); //Creates a red color.
var Blue = CreateColor(0, 255, 0); //Creates a blue color.
var Blend = BlendColorsWeighted(Red, Blue, 2, 1); //Creates a reddish purple color by blending the two colors with 2 parts red to 1 part blue.BlendColorsWeighted can be adapted for the more familiar alpha blending method as follows:
//Alpha can be between 0 and 1
function AlphaBlend (Color,SourceColor,Alpha) {
Alpha = Math.min(Math.max(Alpha,0.0),1.0); //Clamp alpha to 0-1
return BlendColorsWeighted(Color,SourceColor,Alpha,1.0 - Alpha);
