The difference in color between the wig you received and the image on your screen could very much be due to the settings of your computer monitor. You can look at the wig on different screens to check the colors if that will help. (=
I thought that to, but the difference between the screen shouldn't have been that great. o_o
And I did look on my phone too, but it appears the same. I know the coloring would be a slightly different shade but not a drastic change.
