@SergeyKritskiy By using Blending Options -> Color Overlay. But I find, that Photoshop API hasn't api for this stuff

@Ovaryraptor I have a site with t-shirts and wanna give clients opportunity to customize the t-shirt. I have psd file of t-shirt, and need way to change layers in this file. The only thing which can change it, is Photoshop. And I need change layers in psd file, (like colors, positions) then send it to the printer. And only thing I can't do right now - change color on Smart Object using scripting Photoshop.

Hi @Ovaryraptor ! The result is should be like that i.imgur.com/HJVwxFi.png It should be a script, because I need to change .psd files on background (e.g. move compass 20px to right side and change color to blue) automatically.
