Not helpful. Perhaps if the walls in the photo I uploaded were white it might be easier to "paint them". I uploaded a pic of my red kitchen. When I tried to paint it I ended up with a color blend of my current red and whatever color I was trying to paint it. An option to prime would be added work on my end but even painting it white produced pink results.
Pretty easy to quickly visualize your own rooms with new paint colors! Mine did not turn out as perfectly as the pictures but it's still very impressive. Other apps I tried were pretty much useless, this one actually does what it says. Great!
Not perfect, but does what it says Changing colors is NOT a problem; you have full range. I didn't try for real details, but it's not hard to blue-tape a wall as opposed to a room. Zoom would definitely help, though. Yes, it's splotchy around edges, but it does a pretty smart and FAST job of editing out objects. It's not going to be perfect, but it gives you a good general idea. Helps to take a shot with full sun and then color-correct the pic before trying, and a night shot for how that will look under lamp light.
Needs work, a lot of it Not good at all, colour is patchy n won't fill a particular area. Could do with a zoom option
