building colour by "sample colour from photo" #65

would be nice if we could use the Mapillary photos and get the building colour by using a sampling tool while clicking on the building and add it as a attribute on the building. Instead of having to go to the pallet and copy paste the colour code. something similar like "eyedropper" in Photoshop.

You'd need to tweak the color afterwards as well, though, since the color-picked color from a photo – even in sunlight – does not really resemble the actual building color very closely. It tends to have a gray-ish tint to it.

Color code taken from photo depends on lighting, exposition, angle and don't think storing rgb color value have much sense. Maybe store spoken word description like white, red, blue. But anyway I do not plan adding such feature.
