If you're still on the 'white & blue' page, look down in the bottom left-hand corner & find the little paintbrush with 'Default style' alongside it. Click there; then head right, across the page, until you find 'Tactical'; click on that, and you'll change the screen to a lovely black with lotsa orange & some other appalling colour highlights!
I tried it, but I hadta change back when my eyeballs started bleeding so much that I couldn't see the screen!! Personally, I think the 'white & blue' Default is the lesser of two weevils!
