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

Method

Colormix(Color a, Color b, double percent)
Mixes two colours. 
return new Color((int) (a.getRed() * percent + b.getRed() * (1.0 - percent)),
        (int) (a.getGreen() * percent + b.getGreen() * (1.0 - percent)),
        (int) (a.getBlue() * percent + b.getBlue() * (1.0 - percent)));
Colormix(Color c0, Color c1, float amount)
Mixes two colors. 
float r0 = c0.getRed() / 255f;
float g0 = c0.getGreen() / 255f;
float b0 = c0.getBlue() / 255f;
float a0 = c0.getAlpha() / 255f;
float r1 = c1.getRed() / 255f;
float g1 = c1.getGreen() / 255f;
float b1 = c1.getBlue() / 255f;
float a1 = c1.getAlpha() / 255f;
...
Colormix(Color c1, Color c2)
mix 
return new Color((c1.getRed() + c2.getRed()) / 2, (c1.getGreen() + c2.getGreen()) / 2,
        (c1.getBlue() + c2.getBlue()) / 2);
Colormix(Color c1, Color c2)
Mix colors visually: red + green = yellow, etc. 
final float[] b = Color.RGBtoHSB(c1.getRed(), c1.getGreen(), c1.getBlue(), new float[3]);
final float[] c = Color.RGBtoHSB(c2.getRed(), c2.getGreen(), c2.getBlue(), new float[3]);
final float[] a = new float[3];
float h1 = b[0];
float h2 = c[0];
if (h1 < h2) {
    float tmp = h1;
    h1 = h2;
...
Colormix(Color c1, Color c2, boolean useAlpha)
Mix 2 colors without "priority" color 
final int r, g, b, a;
if (useAlpha) {
    final float a1 = c1.getAlpha() / 255f;
    final float a2 = c2.getAlpha() / 255f;
    final float af = a1 + a2;
    r = (int) (((c1.getRed() * a1) + (c2.getRed() * a2)) / af);
    g = (int) (((c1.getGreen() * a1) + (c2.getGreen() * a2)) / af);
    b = (int) (((c1.getBlue() * a1) + (c2.getBlue() * a2)) / af);
...
Colormix(Color c1, Color c2, double f)
Mix two colors by a given amount 
if (f >= 1.0)
    return c2;
if (f <= 0)
    return c1;
double r1 = c1.getRed();
double g1 = c1.getGreen();
double b1 = c1.getBlue();
double r2 = c2.getRed();
...
Colormix(Color c1, Color c2, float bias)
Mixes two given colors. 
if (bias <= 0.0)
    return c1;
if (bias >= 1.0)
    return c2;
if (Double.isNaN(bias))
    return c1; 
float r = mixNumberFloat(c1.getRed() / 256f, c2.getRed() / 256f, bias);
float g = mixNumberFloat(c1.getGreen() / 256f, c2.getGreen() / 256f, bias);
...
Colormix(Color src, Color dst, double factor)
mix 
double fs = factor / 255.0;
double fd = (1.0 - factor) / 255.0;
double r = src.getRed() * fs + dst.getRed() * fd;
double g = src.getGreen() * fs + dst.getGreen() * fd;
double b = src.getBlue() * fs + dst.getBlue() * fd;
int ir = Math.max(0, Math.min(255, (int) Math.round(r * 255)));
int ig = Math.max(0, Math.min(255, (int) Math.round(g * 255)));
int ib = Math.max(0, Math.min(255, (int) Math.round(b * 255)));
...
doublemix(double x, double y, double a)
mix 
return x + a * (y - x);
Colormix(final Color c1, final Color c2, final double factor)
mix 
assert 0 <= factor && factor <= 1.0 : factor;
final double backFactor = 1.0 - factor;
return new Color(Math.min((int) Math.round(c1.getRed() * backFactor + c2.getRed() * factor), 255),
        Math.min((int) Math.round(c1.getGreen() * backFactor + c2.getGreen() * factor), 255),
        Math.min((int) Math.round(c1.getBlue() * backFactor + c2.getBlue() * factor), 255));
