Wooly, you want to use ColorFilter(). (opens in new window)

You need to do something like:

ColorFilter(CF_GREY, screen);

...somewhere in a renderloop. I haven't used it before personally, so someone else could help you better.

So... whatcha workin' on? ;)

Before I found out about ColorFilter() I had made my own function that would average the three R, G, and B values together and then set a pixel of that average in each of the rgb slots. The results were jerky and just didn't work for me. Soon after, I found out about colorfilter and felt like an idiot. Just thought I'd say that I have indeed done something, contrary to what you might think. ;-)

While the ColorFilter is the awesome, recommended way, why does not filling a Rect at RGB(128, 128, 128) at 50 lucency work?
Because that just averages each pixel color with RGB(128,128,128). So if you have a pixel colored RGB(54,134,90), the result after you lay the recfill should be RGB((54+128)/2, (134+128)/2, (90+128)/2), which is not going to be a shade of grey.

This is 128/128/128 being blitted in various ways over a horrendous background! As you will see, cfilter is the only one that produces the desired look.

Thanks a lot! It resolved my problem :) I can now continue working on my game.
