That was an intentional narrative device from Soderbergh though.
From IMDB:
"To achieve a distinctive look for each different vignette in the story, Steven Soderbergh used three different film stocks (and post-production techniques), each with their own color treatment and grain for the print. The "Wakefield" story features a colder, bluer tone to match the sad, depressive emotion. The "Ayala" story is bright, shiny, and saturated in primary colors, especially red, to match the glitzy surface of Helena's life. The "Mexican" story appears grainy, rough, and hot to go with the rugged Mexican landscape and congested cities."

"Inception" took a similar approach, where each dream level had a unique tint.
