Method

double[]RGBtoHSV(double r, double g, double b)
Calculates the HSV color value for a given RGB value. 
double h, s, v;
double min, max, delta;
min = Math.min(Math.min(r, g), b);
max = Math.max(Math.max(r, g), b);
v = max;
delta = max - min;
if (max != 0) {
    s = delta / max;
...
float[]RGBtoHSV(float r, float g, float b, float[] result)
http://www.cs.rit.edu/~ncs/color/t_convert.html 
if (result == null) {
    result = new float[3];
float h, s, v;
float min, max, delta;
min = min(r, g, b);
max = max(r, g, b);
v = max; 
...
float[]RGBToHSV(float... rgb)
RGB To HSV 
float r = Math.min(Math.max(rgb[0], 0f), 1f);
float g = Math.min(Math.max(rgb[1], 0f), 1f);
float b = Math.min(Math.max(rgb[2], 0f), 1f);
float min = Math.min(r, Math.min(g, b));
float max = Math.max(r, Math.max(g, b));
float delta = max - min;
if (max == 0f)
    return new float[] { 0f, 0f, 0f };
...
voidRGBtoHSV(float[] hsv, float[] rgb)
Convert an RGB color to HSV representation. 
float r = rgb[0];
float g = rgb[1];
float b = rgb[2];
float h, s, v, diff;
int minIdx = 0;
int maxIdx = 0;
float maxCol = r;
float minCol = r;
...
voidRGBtoHSV(int r, int g, int b, double hsv[])
Convert r,g,b to h,s,v 
int min; 
int max; 
int delMax; 
if (r > g) {
    min = g;
    max = r;
} else {
    min = r;
...
double[]rgbToHsv(int red, int green, int blue)
Converts an RGB color value [0-255] to HSV [0-1]. 
double r = (double) red / 255.0;
double g = (double) green / 255.0;
double b = (double) blue / 255.0;
double max = Math.max(Math.max(r, g), b);
double min = Math.min(Math.min(r, g), b);
double h = 0;
double s = 0;
double v = max;
...
double[]RGBtoHSV(int red, int green, int blue)
Method returns three doubles representing the HSV values of a RGB input Values in input must be between 0 and 255 Values in output are between 0 and 1. 
double H = 0, S = 0, V = 0;
double R = red / 255.0;
double G = green / 255.0;
double B = blue / 255.0;
double var_Min = Math.min(Math.min(R, G), B); 
double var_Max = Math.max(Math.max(R, G), B); 
double del_Max = var_Max - var_Min; 
V = var_Max;
...
voidRGBToHSV(int red, int green, int blue, float[] hsv)
Convert RGB components to HSV (hue-saturation-value). 
float min, max, delta;
min = Math.min(red, Math.min(green, blue));
max = Math.max(red, Math.max(green, blue));
hsv[2] = max; 
delta = max - min;
if (max != 0)
    hsv[1] = delta / max; 
else {
...
int[]rgbToHsv(int rgb)
Converts the red, green and blue color model to the hue, saturation and value color model 
float r = (float) ((rgb & 0xff0000) >> 16) / 255;
float g = (float) ((rgb & 0x00ff00) >> 8) / 255;
float b = (float) (rgb & 0x0000ff) / 255;
float M = r > g ? (r > b ? r : b) : (g > b ? g : b);
float m = r < g ? (r < b ? r : b) : (g < b ? g : b);
float c = M - m;
float h;
if (M == r) {
...
StringRGBtoHTML(int rgb)
Produces HTML color representation 
final StringBuilder b = new StringBuilder("0000000");
b.replace(0, 1, "#");
for (int i = 5; i > 0; i -= 2) {
    final int bt = rgb & 0xFF;
    rgb = rgb >> 8;
    StringBuilder b2 = new StringBuilder(Integer.toString(bt, 16));
    if (bt < 16) {
        b2.insert(0, "0");
