I've been making lots of progress on my new TLR Professional Photographic Effects Toolkit.

The latest free action set is the TLR Color Overlay action set. The actions apply colored overlays to your images for interesting artistic effects. Your image can be in RGB, CMYK, or L*a*b mode. The actions use Fill Color adjustment layers to reduce RAM consumption and file size.

Available color overlay effects include:

Blue/Sepia
Cyan/Sepia
Emerald/Green
Green/Yellow
Magenta/Yellow
Orange/Yellow
Red/Yellow
Violet/Cyan
Yellow/Orange

These are stronger effects than those in the TLR Split Toning action set, since they are intended to be applied to color images.

Enjoy!
