Is there a way to choose different themes for different questions?

We’re building a rather complicated survey with lots of sections and logic jumps, and it occurred to me that it might help respondents keep track of where they are if we’re able to color code each section. It seems my only options for visual customization are themes (which can only be applied to the whole survey, it seems) or adding images. I might be able to accomplish what I’m trying to do by adding images, but I’d rather be able to just change the color to keep the distractions to a minimum. Anyone know if this can be done? Thanks in advance!
