Search on more general terms: "3D LUT" or "color grading"
I found thousands of samples from web searches while developing the feature - some free, and some commercial.
Of course, the most useful ones were commercial.
Also, there are tools for creating 3DLUTs in After Effects, Premiere and Final Cut : http://www.redgiantsoftware.com/products/all/magic-bullet-lut-buddy/
Is there a way to create custom looks with a specific set of colors?
I do a lot of identity work, and clients often request that we make stock images from different sources look consistent, or even replace certain hues with their corporate PMS colors. Doing it with masks and color ranges is a tedious process, and is often hit and miss. And while Color Lookup adjustments help with consistency, it would be nice to have a tool where I could specify my own color values.
There is no way to create them in Photoshop at this time.
Using other tools, you could create such LUTs (like I did with the pastels and blacklight colors).
(though I have to admit: I wrote my own tools to create most of those LUTs)
