the bulb you used is a 3000k, its kind of yellow, it's very yellowish, it's warm white, for any video projector you need between 5500-6500k cool white, so maybe it's the broblem, and you to check how many lumens you got with this, is the picture is more dark than the originale bulb??
 
I see that you have a DLP 1080p VP, not bad...!
witch is the good picture?

I heard that the problem may be with this lamp, but i do not understand WHY the projector SO distorts the colors.
I think with this lamp i have around 250 lumens with 100" diagonal.
This lamp just for tests, later i want use in this projector xenon 55w.
It's not a 1080p projector, native resolution is 1024x768 ;)

I see, so now you cant judge until you put the xenon 55w with 6000k° to make sure you are using the right white.
if the picture is fine so be it...!
but if not, then you need to investigate further more...
 
have nice day.
