I've re-texturing the city of Solitude in Elder Scrolls V: Skyrim.
I've made the stone walls for buildings a shade lighter. I did this by duplicating the original layer, setting it Screen and added a slight photo filter to the merged texture. I picked a custom colour, a light orange-grey colour, dbb98a in hexadecimal to give it warmth. I went easy on the orange colour because it broke the lore.
I made the wood trim of buildings a more intense brown colour because the original texture looked like driftwood (this is mean to be the capital city after all), a reference to historical viking wood. However, Skyrim is meant to be a cold palace (even though I use a mod that adjusts the saturation and give the game a warm feeling) so unfortunately I had to desaturate the brown a little bit.
This is still a prelude to a bigger mod, I'm going to try to turn Solitude into something like renaissance Florence or Valletta in Malta. To do that, I would have to redo the stone bricks into more square shaped limestone. The orange colour would be more desaturated, and I would have to use a mod to enhance the colour and give it a warm feeling, therefore breaking the lore of Skyrim's cold world. Desaturaion would not work.
