I just purchase this printer a few days ago, after reading all the great reviews. I've only printed a few photos on the Canon Glossy Photo Paper (4x6), and so far I am not impressed with the color. Actually, I am really disappointed.
The quality/clarity and speed of the print is great, but the colors are dull and not at all the the vibrant color seen on the "sample" print in the store. I am spending time now to see if there is some other setting to use to improve what I am seeing. I don't want to have to color correct every photo.
I also didn't buy higher quality paper yet, just in case...I'm not sure how much of a factor that would play in the vibrancy.
