I get the same result with the colour image and a slightly better result 
with the gray image:

'rwENTYslx

GASOLINE

STATIONS 

The letters are quite small and I was surprised that tesseract was so 
successful: a resolution of 300dpi is normally recommended for input.

I made a test file using a red font and larger text and tesseract was able 
to read it but not very well. The short answer seems to be: Tesseract works 
better with grayscale images.
