How to get the colour name by RGB value?

Java: How to get the name of colors in Java from Hex or RGB values?

• Hi, The problem is that I need to get the names of colors using Java.  I got the hex values and the RGB values of where ever the cursor goes.  I tried using the hex value and match it to a file of hex values with their color names but only white and grey are being displayed, none of the other color names are showing up.  I noticed that some of the hex values given by Java are not matching the ones in the file.  Same problem with the RGB values.  Is there a way that I can use the RGB or hex values, that I get from Java Color class, to get the color name?  Any open source library or anything that could get me the color name from hex or RGB values? Thanks

  Those colors specified in "java.awt.Color" are just shortcuts for readily available colors.  Given the RGB values (let's say 50,100,75 for example), you can just create a Color instance of that exact color. Color c = new Color(50,100,75); If you actually wanted the names, and wanted it to conform to the definitions of the colors specified by this class, you'd have to iterate over each of the colors and compare.  And the annoying part..is that those colors aren't defined in a fancy-shmancy enum... so you have to construct your own list (or use some even fancier but horribly-engineered reflection).  So to keep it simple: import java.awt.Color; public enum JavaColor { RED (Color.RED), BLUE (Color.BLUE), GREEN (Color.GREEN), ... Do all the colors ... private final Color color; // in meters Planet(Color color) { this.color = color; } public Color getColor() { return color; } } Color myColor = new Color(50,100,75); Color javaColor = null; for(JavaColor jc: JavaColor.values()) { if(jc.getColor().equals(myColor)) javaColor = jc.getColor(); } if(javaColor == null) { System.out.println("Your RGB values don't match any Java colors."); } else { System.out.println("Your RGB values match the Java color \"%s\".",javaColor); } Using Strings with hex values is not much different, but java.awt.Color only provides constructors to handle RGB, so you'd need to convert it first: http://stackoverflow.com/questions/4129666/how-to-convert-hex-to-rgb But just copy and paste that :)
