Description

The list of methods to do Color Mix are organized into topic(s).

Method

intmix(int a, int b, int amt)
mix 
return a + (((b - a) * amt) >> 8);
PaintmixColor(Paint p, double value)
mix Color 
if (p == null || !(p instanceof Color))
    return p;
Color c = (Color) p;
return new Color(c.getRed(), c.getGreen(), c.getBlue(), ((int) value) * 255 / 100);
ColormixColors(Color a, Color b, double r)
mix Colors 
double s = 1.0f - r;
return new Color(boundColor((a.getRed() * r + b.getRed() * s) / 255.0),
        boundColor((a.getGreen() * r + b.getGreen() * s) / 255.0),
        boundColor((a.getBlue() * r + b.getBlue() * s) / 255.0));
Color[]mixColors(Color c)

Returns an array of 9 colors which one could use very good together.

The code to calculate the colors is taken from Twyst .
I've just translated it into Java.

Color[] result = new Color[9];
result[0] = c;
double[] hs = RGBtoHSV(c);
double[] y = new double[3];
double[] yx = new double[3];
double[] p = new double[3];
double[] pr = new double[3];
p[0] = y[0] = hs[0];

ColormixColors(List colors)
mix Colors 
int red = 0, green = 0, blue = 0;
for (Color color : colors) {
    double colorCount = 0;
    if (color.getRed() > 0)
        colorCount++;
    if (color.getGreen() > 0)
        colorCount++;
    if (color.getBlue() > 0)
...
ColormixColorWithAlpha(Color base, Color mix)
mix Color With Alpha 
if (mix == null)
    return base;
final int a0 = mix.getAlpha();
if (a0 == 0) {
    return base;
} else if (a0 == 0xFF)
    return mix;
final float wm = (float) a0 / 0xFF;
...
ColormixedColor(Color originalColor, Color overlayColor)
mixed Color 
final float[] hsbColor = Color.RGBtoHSB(originalColor.getRed(), originalColor.getGreen(),
        originalColor.getBlue(), new float[3]);
;
final float[] hsbError = Color.RGBtoHSB(overlayColor.getRed(), overlayColor.getGreen(),
        overlayColor.getBlue(), new float[3]);
final float[] hsbMixed = new float[3];
hsbMixed[0] = hsbError[0];
hsbMixed[1] = min(max(rangeLimit(hsbColor[1], hsbError[1], 0.3f), 0.5f), 1.0f);
...
ColormixOver(Color backColor, Color frontColor)
Mix 2 colors with priority color 
final int r, g, b, a;
final float frontAlpha = frontColor.getAlpha() / 255f;
final float invAlpha = 1f - frontAlpha;
r = (int) ((backColor.getRed() * invAlpha) + (frontColor.getRed() * frontAlpha));
g = (int) ((backColor.getGreen() * invAlpha) + (frontColor.getGreen() * frontAlpha));
b = (int) ((backColor.getBlue() * invAlpha) + (frontColor.getBlue() * frontAlpha));
a = Math.max(backColor.getAlpha(), frontColor.getAlpha());
return new Color(r, g, b, a);
...
PaintmixWith(Paint paint, Color mix)
mix With 
if (paint instanceof Color) {
    Color c = (Color) paint;
    return new Color((c.getRed() + mix.getRed()) / 2, (c.getGreen() + mix.getGreen()) / 2,
            (c.getBlue() + mix.getBlue()) / 2, (c.getAlpha() + mix.getAlpha()) / 2);
} else if (paint instanceof TexturePaint) {
    BufferedImage texture = ((TexturePaint) paint).getImage();
    BufferedImage mixed = new BufferedImage(texture.getWidth(), texture.getHeight(), texture.getType());
    for (int x = 0; x < texture.getWidth(); x++) {
