P: Can the color Yellow or the green be a little more vibrant or bright?

[Steve Gandy]

I use the colors for particular classifications as most probably do....

If images are marked yellow and green and they are not selected, the colors are are too close and easily confused.

I understand the dulling of the colors when images are not selected is good, you don't want bright colors when you are scanning a grid or the filmstrip....but if you are looking for the yellow or the greens it is easy to get mixed up. Mix ups mean time lost, time lost means money lost.

If the yellow and green are right next each other, it is plain enough but if either of those colors not near the other one, it easy to get mixed up.

I take it that you're talking about the grid cell label color.

You can change the tint from the default 20% to 50% in the Library view options dialog. Press Ctrl (Cmd) + J to open it.

You can't adjust individual colors – it will affect all of them.
