Film where colour fades throughout to represent dying protagonist?

Question

Ok, I can usually find things using Google but no luck this time!This is a film from around mid-90s I think, but could be +/- 10 years. Male lead, who I think gets a kind of lethal injection which has so long to take effect. Or it may be a disease which is killing him.But either way - he has a few hours to achieve his objective.One of the defining things is that **as he gets weaker/the film progresses - the colour fades** - so towards the end of the film it is more black and white than colour.

Answer 1

Hmm...that isn't much to go on, but are you talking about the 1988 remake of "D.O.A." starring Dennis Quaid, where he gets a lethal injection and has a short span to find out who and why before he dies? The original was better, in my opinion.
