ermgravy;4956446; said:Color variation in jar's is caused by two things.
1. Tank back ground. darker/lighter colors will affect tone of the jar.
2. Diet, a high protein pellet an MP diet will help bring out more of the pink-red tones.
Lighting setup also affects a jars color but only while the light is on. that is obvious and an outside eliment but doest effect photos!
this is well documented on these forums if only people tried the search feature...
as evident by the Black Jar in a white setup (page 2), there seems to be conflicting theories in regards to the environmental factors.
however i think it is universally accepted that foods such as shrimp enhance reds. and i did note this in the post.
i searched this whole forum, yes all the 100's of posts on jardini color, which was in fact the reason why this thread came into existence.
