The title doesn't explain my problem as accurately as I'd like, but there's just no other way I can word it.
I'm using Photoshop CS5. I made a group of layers at the bottom of my image that all have gradients and drop shadows applied without global lighting of any sort.
I copied the whole group and placed the layers at the top of my image, but the layers on the top all appear to be darker shades of purple than the set on the bottom. It's hard to notice in the photo, but if you turn your brightness all the way up and really look at it, you'll notice the difference.
The funny thing is, I placed the top set directly next to the bottom to see if they were different, but seeing as I copied and pasted them, sure enough, they are exactly the same.
This literally makes no sense to me and if anyone has any insights, I'd greatly appreciate it. It's imperative that these sets are the exact same shades, or it won't doesn't look right with the true background. I didn't include the true background in the photo because it's still noticeable even with a black background.
