User: Can you recommend colors that are easy on the eyes for long period of time?
Assistant: Hmm, I think the main thing here is to avoid highly saturated or contrasting colors, since these can be quite fatiguing to look at.  I would recommend shades of grey, light blues, and muted greens, along with some earth tones such as browns and beige.  Overall, a more muted or toned-down color scheme is probably best for reducing eyestrain.  Hope this does the trick!  Good luck!
