No idea but I would be surprised if there was:-1) It is so hard to identify colour from an image2) The colours on real resistors do vary wildly3) It is so stupidly easy to do yourself.
Yes, I was taught the 'raw' version in the Air Force, no women in our class, but I'm sure they have changed that sense. However between my aging eyesight, and the many extra color bands added these days for various who knows reasons, and the weird shades of colors used sometimes these days, I always, always, measure the resistor as a final check. I have a good quality fluke model 45 bench DVM so I tend to trust it more then my eyesight. Wanting a smart phone to tell me the value of a resistor is just very very stupid in my opinion. If you don't own a decent DMM then you shouldn't be playing with resistors in the first place.Lefty
