white/black do not change well

[DTrejo]

some feedback: when I wrote change white to blue, it ignored the obvious white shirt and instead made the skin blue!!! very strange. But I know you are working on this. Colors as one can see, are hidden within other colors; yellow is in orange , etc so how would one differentiate as one works on a photo to change the colors? Ex: I ordered it to change yellow to blue and all the trees turned blue!!! It's fun though!! Love ya, mom
