My buddy had 3 looked just like this one about 10 years ago. 2 females looked even darker, almost chocolate brown. The male had very little yellow tinge in his skin when in good light. Those were the geckos that got me started on my gecko train. I then bought a high yellow and a patternless with a great yellow back. Moving about 7 years ago I had to find those girls homes. But never gave up trying to find a normal that looked that dark again.
This post makes me want to search again.
