Method

StringcolourToRgbString(Color colour)
colour To Rgb String 
return new String(colour.getRed() + ", " + colour.getGreen() + ", " + colour.getBlue());
StringcolourToString(Color colour)
colour To String 
if (colour == null) {
    return "extend";
} else if (colour.getAlpha() == 0) {
    return "transparent";
return String.format("#%08X", colour.getRGB());
StringcolourToString(java.awt.Color c)
colour To String 
return Integer.toHexString(0xFF000000 | c.getRGB()).substring(2);
StringtoRGB(Color c)
convert this color as "rgb(red,green,blue)" 
if (c == null)
    return null;
return "rgb(" + c.getRed() + "," + c.getGreen() + "," + c.getBlue() + ")";
StringtoRGB(Color color)
Turns the color into RGB notation ("R,G,B" or "A,R,G,B" with A/R/G/B ranging from 0-255). 
if (color.getAlpha() < 255)
    return color.getAlpha() + "," + color.getRed() + "," + color.getGreen() + "," + color.getBlue();
else
    return color.getRed() + "," + color.getGreen() + "," + color.getBlue();
inttoRGB(ColorSpace colorSpace, float... components)
Returns an rgb value from color components in the specified color space. 
float[] rgb = colorSpace.toRGB(components);
if (rgb[0] < 0f || rgb[1] < 0f || rgb[2] < 0f || rgb[0] > 1f || rgb[1] > 1f || rgb[2] > 1f) {
    return 0;
return 0xff000000 | ((int) (rgb[0] * 255f) << 16) | ((int) (rgb[1] * 255f) << 8) | (int) (rgb[2] * 255f);
inttoRGB(int red, int green, int blue)
to RGB 
return new Color(red, green, blue).getRGB();
shorttoRGB565(Color c)
Returns a color in the RGB565 format based on a Color instance. 
if (c == null) {
    return 0;
short rgb = (short) (((c.getRed() & 0xf8) << 8) | ((c.getGreen() & 0xfc) << 3) | (c.getBlue() >> 3));
if (rgb == 0) {
    return 0x20;
if (rgb == 0x20) {
...
inttoRGBA(Color c)
to RGBA 
return c.getRed() | c.getGreen() << 8 | c.getBlue() << 16 | c.getAlpha() << 24;
StringtoRGBFunctionCall(Color color)
to RGB Function Call 
StringBuffer sbuf = new StringBuffer();
sbuf.append('#');
String s = Integer.toHexString(color.getRed());
if (s.length() == 1) {
    sbuf.append('0');
sbuf.append(s);
s = Integer.toHexString(color.getGreen());
