color in the items table

[Dymerius]

I would like to change the tint of some armor pieces (not dye) and I'm just curious how to manipulate the color field in the items table to get a desired result. All I really know so far is:

1 = Black

As the number increases, color goes through dark blue, then I haven't really tested it after about 500.

2147483647(max value) = White

I know higher values are... lighter in color... but I really need to understand how this variable works so I don't have to sit here trying every single number combination :p

Any suggestions?

Thanks in advance,
