do you know of any colour refrence I can work from?, the colour decimals 1.0,0.6 etc are hard to work out.

This is for your streetlights?

What colour were you looking for?

Col. Kilnks Radian and Color Utility is perfect for this.
The only problem is I cant remember where I found it  :-\
Id suggest searching some ofp sites for it.

There is a simple way to work it out:

This is how the colour values are derived... the RGB palette has originally a range of 0-255 for each channel.  However, in the code form, 0-1 is used instead.

Now let's read the line again,
colorText[]={0.23,0.3,0.08,0.75};

Knowing that, one can easily convert these values to and fro.

  R channel : 0.23/1.00 * 255 = 58.65
  G channel : 0.3/1.00 * 255 = 76.5
  B channel : 0.08/1.00 * 255 = 20.4

I usually round up the numbers.

So, in your picture editing program, if you open up the colour palate, you'll see the boxes for the RGB values and can work them as following:

eg.   R = 59                      59/255 = 0.23
        G = 80     then         80/255 = 0.31
        B =  2                        2/255 = 0 (or 0.007)

And that's how you get your colours.
