It seems lilliput's algorithm for compressing PNGs is causing them to become noticeably desaturated compared to the original image. I also tested Google's Hangout's compression algorithm which didn't result in desaturation (incidentally lilliput's file size is also ~25% larger than Google's)

Examples

Original image (105 kb):

lilliput compression (via Discord) (95 kb) (notice how the red and green are desaturated vs the original):

Google compression (via Google Hangouts) (76 kb):
