been working on a background tile set:
the grey background will be some sort of parallax I think. the background tiles that are not part of the parallax will look better once i finish the sloped versions as will the ceilings sloped versions.
also playing around with water i quite like this simplistic solid colour at the moment
I have made several attempts to tweak the colours and contrast in the various ways suggested but it always ends up looking either awful or so close to the current colour that its not worth changing.
maybe i just don't have a very good 'sense' of how colour works but i seem to disagree with allot of suggestions to increase contrast.
i also created an 'under ground detail' tile to try and break up some of the black area.. though i am not to sure if it looks any good.. maybe there is a better way to break up the black.
