Because blue is the most popular colour in the world
, I believe that the most popular colour in the world is : Blue. Because it suits boys and girls and it can be a nice suttle colour that is not to strong on the eye. Thankyou :) x
Light blue in most games but in Sonic Heroes she has hot pink eye shadow.
Some people use eye shadow because: -Their eyes 'pop' when they use the eye shadow colour. -It adds a beautiful colour to their face. -It completes the look ...and more! Hope this helped! x

Im not sure what the most popular eyeshadow color in Africa is but I would guess bright colors such as orange and yellow and those kinds of colors but again I'm not sure. Hope I could help.  Greens and blues look very pretty when they are well incorporated.
blue
I would say copper
A goldeny brown colour is best ;)
Purple is the most uncommon eye color
Shimmery gold, I suggest. Hope this helped! x
