 Posted: Tue Jul 02, 2002 9:54 pm Post subject: Fluxbox style making |
 |
|
I've waded through the man pages for fluxbox and X. I'm trying to figure out setting up colors in flux. For example:
| Code: | | toolbar.button.color: rgb:CC/CC/CC |
I've found /usr/X11R6/lib/X11/rgb.txt which includes stuff like this:
man X(7) indicates: | Quote: | An RGB Device specification is identified by the prefix
"rgb:" and has the following syntax:
rgb:<red>/<green>/<blue>
<red>, <green>, <blue> := h | hh | hhh | hhhh
h := single hexadecimal digits
Note that h indicates the value scaled in 4 bits, hh the
value scaled in 8 bits, hhh the value scaled in 12 bits,
and hhhh the value scaled in 16 bits, respectively. |
What I don't understand is, how to find what color 'CC' equates to. Anyone have any ideas? I've tried Google, but
haven't hit the magic keywords yet.

CC is merely the red value (in hex) part of the RGB value. CCh=204d
So CC/CC/CC =
204red/204green/204blue
Those three colour values combined result in a grey colour. If you've got KDE installed, kcolorchooser is a good tool to convert a hexadecimal RGB code into a visible colour. |

This part I understand, but I was hoping to find a conversion table or formula to come up with:

Thanks for the tip, but I try to avoid KDE and accessories. I can't recall the steps to convert.
Maybe my real calculator will do that.

It's just standard hexadecimal; i.e. converting base 10 (decimal) to base 16 (hex). Ask Google.
| Code: | Dec Hex
0 0
1 1
2 2
3 3
4 4
5 5
6 6
7 7
8 8
9 9 (confused yet? hee)
10 A
11 B
12 C
13 D
14 E
15 F |
So... how do I convert 171d to hex? Divide by sixteen. That yields 10, with a remainder of 11. So, 171d = ABh.
How do I convert ABh into decimal? A * 16 + B => 10 * 16 + 11 = 171d.
See?

I knew it was simple... thank you. Has been too long since I've done any of that.
Maybe I should enroll in a class (and get the student discount for VMWare )

If anyone else wants to know, Gimp also does the hex conversion.
