As mentioned above from the wonderful members of Arachnoboards, LQ vary in color patterns and degree of shades to there color dependent on the locale of the region they are from, I have one from Somalia and a friend of mine has one from Egypt and they look different in terms of color/shade but they are the same specie, also mentioned is there are quite a few Leiurus species that look very similar but are in fact different species! I have attached a couple pictures to show the similarities in 3 different species! I got these images from https://www.ntnu.no/ub/scorpion-files/ which is a great source of information!
