I want to say that it very well looks like a Tokay, but it's hard to distinguish the patterns and the colors due to the picture (I was thinking the picture and the lighting was making it seem more tan than it really is, but I could be wrong).

Golden gecko could be a possibility, but from the golden gecko pictures that i've seen, the distinguishable patterns just don't match up. Tokays have the ability to change colors (usually from a more darker color to a lighter color), so try and see if you can catch it on some days where it is a different shade of color, and get better pictures to post and compare.

http://www.geckoweb.org/profiles is a great resource to identify your gecko, and from the Tokay picture it has on this website, the Tokay actually looks like it has more of a tan body than a bright blue (or that might be the lighting used they took when taking the picture?)

If you could provide more accurate pictures and close ups of certain details, we might be better able to identify it!
