Hi Guys,

I think some understood my requirement and some didnot.

I will explain it in a simple way :-

a) I got a web site.
b) In the site i have a page where i can set the color settings.
d) I should be able to set my background color,Body Color,Button color,Link
color
e) I am entering the hexadecimal code, which can be even selected froma
color picker javascript.
f) Now if i give my background color has light and also my link color as
light i may not be even seeing certain links.

I am providing these options to the users, so that they can customize there
colors.
Now suppose a user changes certain color combinations , he may not be able
be see certain facilities like

if you give Body Color : FFFFCC
and Link Color :ffffff

which i want to avoid .

Thanks for all the reply

Regards
Vinod
