Color Tracker Tool

There have been many times where I have to see the color in a portion of a video and animate a different layer's fill color accordingly. Helps when doing a clean plate of not-that-noisy, filled-with-solid-colors moble game footage. Its easy when the color changes twice or thrice in a 30 sec bit but its ridiculous when there's 10 something in-betweens. Just like the motion tracker tool, I think the animators around the world could use a dnamic color picker tool (Or let's call it Color Tracker) that reads color of a selected pixel against frames and transferes it to a Null object (I know Null objects don't have the color property - maybe we should add it for the data to land somewhere) or a more appropriate layer that we could apply the data to. 

I am a marketing artist/ motion designer for mobile games and I know atleast 20 people who have been missing this feature from their everyday work.
