I downloaded a sample product of yours “POSTER”. 

And when you make design on frontend i add text but there is no color picker for text. Where is it pls?

How add a color picker for the customers to change their added text objects?

If you look at the attachment you will see there is no option to change the color of the text...

I have the same problem. 

Rady Kal, the problem is in the text, your solution it ok for images an designs.

in the screeshot you will see there is no option to change the color of the text...
