I'm in a pickle.
I have to make form controls (buttons, checkboxes, text inputs, etc.) on a semi transparent black background (85% alpha).
Here's what they look like so far:
Notice the difference between the top two and the bottom two. The difference is the bottom and right border is just light enough to give that cool inset look. The problem? All but one of those borders is the same color.
Because it's on a transparent background, the lines appear to your eye as either lighter or darker based on the color behind it! So, that neat inset look will come and go based on what's under it. I always want the neat inset look to be there, how can I do it? Are there any blend mode tricks for this?
P.S. I forgot to mention that this will eventually get to be displayed in Flash, so I get to have a little fun with blend modes and stuff.
Edit: I made another image to better clarify the issue (by 'too dark' and 'too bright' I am still referring to the right and bottom borders).
