Hmm... not sure if this is a serious question or not... sounds 
answerable though so I'll give the benefit of the doubt (:

Nope, if you have a large enough amount of DNA that you can see it, the 
DNA is transparent! It has no colour.

The green and brown colour of algae is probably due mostly to 
chlorophyll, which is a pigment that absorbs sunlight for the conversion 
of sunlight to energy. They use it to 'power' their cells so the can 
move, reproduce etc. They're some of the original 'solar cells' (:
