The hi-res "color" tiles are a nice addition. Agreed the red states are hard to look at, but AZ isn't really that colorful or true to color either. Looks pretty browned out to me and dark. The hi-res color urban tiles around the Tucson area are some of the best I've seen, but I believe they were commissioned by the city or county and were not done over wide areas. Not sure how they ended up on Terraserver, but glad they did.
I don't know if this would be simple to add or not, but it would be nice to have the new color tiles available in the Show/Download tiles table. Although if you think this might tax the server too much and risk not being able to use it in the future, I'd leave it for manual downloads. (BTW, it looks to me that after downloading tiles, the rectangle of the download remains on the screen, even when a different tool is selected.)
On a related note, it would be nice to be able to adjust the brightness/contrast for this tile set in a way similar to how it is down with the combo tiles, or maybe just add it as an option in that feature.
I am enjoying the new set of images. Always fun to go to your favorite places to see what new views there are.
