Not sure on the first one but the second one is a nimbochromis, either a livistoni or possiable venustus, hard to tell for me when they are that small.
About the color, the fish could be in a stressed state, or the light in the photo has just washed out the fishes' color. However, I did forget about the spots! Good eye!
i have other plans for the livingstoni
shall try and get anothr pics of the previous fish
actually the fellow in the pic gets picked on by the similar fish and that fellow is in much better colors but he is too fast to take pics of
gonna give a single tank for the livingstoni
shall PM you once i get a better shot and have uploaded it
