Depends on the amount of solution you use.
My kits say use 2 drops which is far too little and looks barely green. I 
used 5 drops and it looked dark green and then light yellow after a 50% 
water change.

I'll have to take a photo of it in the two states and convert to monochrome 
to see the contrast difference if any.
