Are there any published guidelines for developing colorized console apps? |
| 8 |
Perhaps something like: |
| 9 |
|
| 10 |
1. If you change the foreground color, you must change the background |
| 11 |
to a contrasting color so the character is still visible. (i.e. |
| 12 |
don't assume the default background color is constrasting) |
| 13 |
|
| 14 |
2. Remember that 10% of men (and some women too) are color-blind when |
| 15 |
chosing your colors. |
| 16 |
|
| 17 |
3. Consider using bold, underline, and/or reverse video instead. (folks |
| 18 |
with dumb terminals for consoles will thank you) |
| 19 |
|
| 20 |
4. Only use color, reverse video, etc. when doing so conveys additional |
| 21 |
information to the user. (i.e. don't make body text green just |
| 22 |
because you like green) |
| 23 |
|
| 24 |
5. Stick with plain text if you're not outputting to a tty. |
| 25 |
|
| 26 |
6. There is NO rule six. |

I use black text on white background (you know, the default colors for |
| 30 |
xterm, gnome-terminal, konsole, etc.) and still have trouble reading |
| 31 |
the output from certain Gentoo-specific commands, most notably java-config. |
| 32 |
portage -v output looks like fruit salad (light green package names on |
| 33 |
a white background? Why change the color of the package name at all? |
| 34 |
I've never seen it be anything but green.) |
| 35 |
|
| 36 |
Yes, I know about NOCOLOR and java-config -n. I don't want to get rid |
| 37 |
of the colors, I'd just like to see them used with a bit more care and |
| 38 |
subtlety. |
