MS Paint/Photoshop Custom color filling issue

Hello,

I defined a custom color in MS Paint.

R -> 255
G -> 204
B -> 051

I then tried to fill in an arrow image (webresource.gif) that shows up
on an asp:menu control (microsoft asp.net) with this color. But nothing
happened.

I tried it on Photoshop as well and it didn't work either.

Is there a way around this?

What is so peculiar about this color that Paint/Photoshop are both
stumped?

Thanks,

Burak

Just a guess but ... there's nothing peculiar about this color if you
are in RGB color mode, but .gif files are in 'indexed color' mode and
are limited to a total of 256 colors (8 bits) so this custom color (24
bits) doesn't apply to gif.

Convert the mode of the gif file to rgb color, apply the color and then
convert back to gif (indexed color). That should work ...

Bill,

Could you tell me how to Convert the mode of the gif file to rgb color,
apply the color and then
convert back to gif (indexed color). ?

I do not know much about mspaint or photoshop.

I have mspaint on my PC but only one other person here has photoshop so
if you could tell me how I could do this in mspaint, I'd appreciate it.
If not, tell me how to do it in photoshop and i can ask that person if
he can do it for me.

Thanks,

Burak

Image - Mode - RGB color (Photoshop ... don't know mspaint)

> apply the color

Select the area you want to fill, click on the foreground color icon
near the bottom of the Toolbox to pull up the Color Picker and enter
the RGB values for your new color, then Edit - Fill and 'contents - use
- foreground color' in the Fill dialog box.

> convert back to gif (indexed color).

A couple of ways to do this but I'd just do File - Save for Web and
pick the GIF option ... then you have some choices for number of colors
to save, different palettes etc so it's best to read the Help files if
you are unsure what you need for a particular image.

Not familiar with that program, maybe someone else can help you here
....

A GIF can contain only 256 colors. If you save a GIF, then you try to
edit the GIF before turning it to RGB, you can not add new colors to it
if the color table is full.

Convert the GIF to RGB, change the colors, then convert it back to
indexed color.
