Any way to change text message theme for lg escape 3?

[AC Question]

I recently updated from lg optimus L70 to a lg escape 3. I use to be able to change text background, colors, etc. Now I notice this lg escape 3 doesnt not have the option from what i see. Optimus you would go to message settings and go to conversation theme, however the escape doesnt have any option like this. Any way to change text themes or am i stuck with this boring theme it came with?
