Hello Everybody,

At the moment I am trying to create an Java Application to convert RGB to RAL. So people from the "paint world" now what colours the one from JColorChooser are in RAL. I have 191 RAL colours with RGB and HEX values.

Here is my code:

public class RAL {
	private int r, g, b;
	private static String[][] RAL = { // RAL-code - Rgb - rGb - rgB - HEX - Color name in dutch \\
		{ "1000", "203", "185", "141", "0xcbb98d", "Groenbeige" },

RAL code:7004 R:152 G:153 B:155 Naam: Signaalgrijs
RAL code:7036 R:145 G:143 B:144 Naam: Platinagrijs
RAL code:7042 R:139 G:145 B:145 Naam: Verkeersgrijs
RAL code:7045 R:135 G:143 B:146 Naam: Telegrijs 1

What I want, is that only one of them will show up. And the most equivalent one. So when:
154, 93, 201 is sended from JColorChooser
170, 83, 180 is the first one it finds
180, 102, 213 is the second, and
145, 77, 207 is the third

I want it to find the one who match the most (I taught it is the third). I hope anyone can help me with this one?

Never heard of RAL before
What is the algorithm to convert RGB to RAL
One thing for sure, I would create RAL object which look like this:

class RAL {
	int code;
	int r, g,b;
	int value;
	String name;

   // constructor
   RAL(int code, int r, int g, int b, int value, String name) {
	   this.code = code;
	   this.r = r;
	   this.g = g;
	   this.b = b;
	   this.value = value;
	   this.name = name;
   }

You should put your values in 6 different arrays and then you can make an array of these Object

	 int[] code = {1000, 1001, 102, 1003, ....
	 int[] r = {203, 204, 205, 244, ....
	 int[] g = {185, 176, ....
	 int[] b = {141, 137, 116,...
	 int[] code = {0xcbb98d, 0xccb089, 
	 String[] name = {"Groenbeige", "Beige",...

	 RAL[] ral = new RAL[code.length];
	 for(int i = 0; i < code.length; i++) {
		ral[i] = new RAL(code[i], r[i], g[i], b[i], value]i], name[i]);

then you RAL objects should have a method to check how it match

for(int i = 0; i < ral.length; i++) {
	int match = ral[i].isMatch(r, g, b);
}

RAL[] ral = new RAL[191];

The problem is there is no existing algorithm (I guess(Not as far as I know)).
RAL is just a system for painters to now what colour they need. Or for a warehouse to show what colours of paper-hangings they have.
This is an example of a chart you can choose the RAL colours.

The RGB in de array are equivalent to the RAL in the same array. So I need to check which RGB is closest to the one is chosen in the ColorChooser.

The method isMatch you were talking about should contain an `algorithm` to calculate what colour looks the most like the RGB what is chosen.

I think I will try to check the differences between all numbers, and which difference is the smallest will be the best option to be the `RAL-match` for the RGB colour which is chosen by the user.

Thanks for your reaction, and you will hear from me if it works .

You should calculate the distance between your color and all the color you know and take the smallest.
See your color as vector.

I hope it helps.

Yop thois should work

consider r,g,b as a x,y,z coordinate in a cube
do the same thing with your RAL and see closest to which one you are

Thanks, will try this, tonight.
Sorry for my late reply.

The class is a little bit different then you told me what was the best form, but it works .

It's only a bit slow, can this be fixed somehow? It is not really necessary, but would be nice.

Thanks for the help you two gave me.
