TWS is terrible at letting you personalize the appearance of things. It's a real nightmare to deal with colors. I tried to put it in white too but it's just nowhere as clean as DAS or TradingView lets you do it.
Also, I've never seen a Times & Sales so useless... can't get the text to be in color like in DAS. I'm really considering the switch to DAS but I'm afraid I'll miss some stuff like the fact that I can place trades directly on the chart with a shortcut and a mouse click.
