Yes. I think you mean "more contrast". There are other ways to improve 
contrast without changing the luminance. It's a problem with visual 
perception that's hard to deal with, and with much research behind it. 
As an example here's a quick color study comparison of the wiki link 
color and my current link color...

http://redshift-software.com/~grafik/boost/color.htm

The wiki color is on the left, mine on the right. The first three rows 
are the pure color. The second three are the luminance of the colors 
only. Both have the text in white and the opposing color. This helps 
show differences, and more importantly similarities, in the brightness 
and contrast of the colors. (this is a common way of typeset comparison)

As you can see the wiki color has slightly more contrast on the white. 
But it has less contrast when only the luminance is considered. One 
common cause for this is the color bleeding that happens on monitors. 
For others the experience will vary, including laptop LCD users which 
are likely to see either no difference or significant difference between 
the two depending on how the LCD does a "floor" or "ceiling" on the colors.

It's wikipedia... and your graphics card.. and your gamma curve.. and 
your monitor, LCD, plasma, or projection.

My suggestion, for you and others, is to download the above page and 
play with the colors yourself to see how it looks on your display. And 
tell everyone of your experience :-)
