Bloopy, sure I did, they are far apart on the visible spectrum, the difference would be one in wave length 340 nm for red and 750nm for violet (if I recall correctly).
Nice image, Rok
Bloopy already gave the answer, but you and ropa were still guessing, so i thought I'd see how long it would take you. Here are the other photos I took.
You can see the shadow of the space shuttle, even in original picture. The plane looks a bit too big to be just one and there's a red carpet laid down alongside it which draws attention to it. If you put these together, you can recognise the NASA logo on the left wing.
Bad quality photo, I know, the plane was turning over the ocean and I could barely see it, but look on the right side.
This was taken from the ground during the final landing attempt of the Endeavour. It's currently in a museum in LA and it was the last space shuttle in use; the US has discontinued the use of space shuttles. I count myself very fortunate for having seen this, even more so because my vacation was not at all planned to include this.
