I actually quite like this wall, but the color banding was driving me nuts. This is my admittedly quick solution, aka add more noise. TS3 really hates solid colors. This is also saved as an 8.8.8.8. ARGB (uncompressed file) to preserve as much quality as possible (larger file size due to this, but I don’t think it’s too bad).

This will conflict with anything that changes the Wall_Moulding_Baseboard multiplier texture.

❗ Disclaimer: There is some wonkiness with this. It doesn’t seem to take effect in certain situations. I could not use solid colors on both the baseboard, and the top bit, otherwise it would still show EAs original texture (under normal circumstances I wouldn’t use it like this, but I wanted to for preview pics which is also why the second pic has a wood pattern on the baseboard). You also will probably need to take this in to CASt to get it to update on existing lots, or potentially for existing presets even. You’ll have to mess around with it. I did a quick test to see if it would survive saving, and exiting the game, and it did.

Basically, use at your own risk.
