Using Photoshop, I created a transparent patterned background (gray scale w/Luminosity blend mode) on top of another layer which is a solid color. Now the developers I’m working with need just the “transparent patterned background” so they can simply change the underlying color as needed. The problem is that they are simply overlaying the “transparent patterned background” and without the ability to apply that “luminosity blend mode” the result is muddy and missing the pop of the original. I tried playing with curve adjustment layers and others but can't seem to get the same result. I personally don’t think it’s possible to give them what they need and still get the same results as the original. Below is an example of the two results.
Does anyone have any idea what I’m dealing with and is this even possible?
