Yeah, the Hindu backgrounds are usually a different shade regardless of color. The red backgrounds stick out a lot more than some of the other variations though.

Notice the different shades of blue on my Waddells. Also, Wallace's uniform looks brown on the Hindu, and gray on the Sovereign, and the Sovereign has more pronounced shading on his neck.

Clarke and Willis portraits tend to look a little on the purple side with a hindu back. I didn't have any comparisons for those cards though.
