Method

java.awt.Colorinterpolate(java.awt.Color a, java.awt.Color b, float portion)
interpolate 
synchronized (s_rvBuffer) {
    a.getComponents(s_aBuffer);
    b.getComponents(s_bBuffer);
    for (int i = 0; i < 4; i++) {
        s_rvBuffer[i] = (s_aBuffer[i] * (1 - portion)) + (s_bBuffer[i] * portion);
    return new java.awt.Color(s_rvBuffer[0], s_rvBuffer[1], s_rvBuffer[2], s_rvBuffer[3]);
Colorinterpolate2Color(final Color first, final Color second, float fraction)
interpolate Color 
final float INT_TO_FLOAT = 1f / 255f;
fraction = Math.min(fraction, 1f);
fraction = Math.max(fraction, 0f);
final float R1 = first.getRed() * INT_TO_FLOAT;
final float G1 = first.getGreen() * INT_TO_FLOAT;
final float B1 = first.getBlue() * INT_TO_FLOAT;
final float A1 = first.getAlpha() * INT_TO_FLOAT;
final float R2 = second.getRed() * INT_TO_FLOAT;
...
ColorinterpolateColor(Color color0, Color color1, double mixer, boolean useHue)
interpolate Color 
if (color0 == null && color1 == null)
    return Color.black;
if (color1 == null)
    return color0;
if (color0 == null)
    return color1;
if (mixer <= 0d)

...
ColorinterpolateColor(final Color minColor, final Color maxColor, final int currentClass, final int numOfClasses)
returns the interpolated color of a color map defined by start and end color. 
final float[] minhsb = Color.RGBtoHSB(minColor.getRed(), minColor.getGreen(), minColor.getBlue(), null);
final float[] maxhsb = Color.RGBtoHSB(maxColor.getRed(), maxColor.getGreen(), maxColor.getBlue(), null);
final float minHue = minhsb[0];
final float maxHue = maxhsb[0];
final float minSat = minhsb[1];
final float maxSat = maxhsb[1];
final float minBri = minhsb[2];
final float maxBri = maxhsb[2];
...
ColorinterpolateRGB(Color start, Color end, float p)
interpolate RGB 
if (p <= 0.5) {
    final float a = 2 * (0.5f - p);
    final float b = (int) (2f * p * 255f);
    return new Color((int) (a * start.getRed() + b), (int) (a * start.getGreen() + b),
            (int) (a * start.getBlue() + b), (start.getAlpha() + end.getAlpha()) / 2);
} else {
    final float a = 2 * (p - 0.5f);
    final float b = (int) (2f * (1f - p) * 255f);
