Method Detail

getClosestColor

public static int getClosestColor(int red,
                  int green,
                  int blue)

Given a RGB value, finds the closest color from the 8-bit palette. The calculation is done using distance in three dimensional space so it's not actually 100% accurate (color similarity is a whole research area of its own) but it's a good approximation.

Parameters:

red - Red component value (0-255)

green - Green component value (0-255)

blue - Blue component value (0-255)

Returns:

Index of the closest color

getAWTColor

public static Color getAWTColor(int index)

Returns the supplied color index as a AWT Color object

Parameters:

index - Index of the color (0-255)

Returns:

AWT Color object representing the color

getAWTColor

public static Color getAWTColor(int index,
                TerminalPalette terminalPalette)

Returns the supplied color index as a AWT Color object

Parameters:

index - Index of the color (0-255)

terminalPalette - Palette to use for the initial 16 color values (index 0-15)

Returns:

AWT Color object representing the color
