[Frameworks] color filters

[Floris Vanhoof]

Dear, 
I play a lot with color filters in front of my 16mm projector lenses.
The ones I use are cheap disco light filters from the electronics store, but some eat a lot of light.
And the amount of light they catch differs. 
For example one stop less with a yellow filter, two stops with a red one and 3 stops with a purple filter.

Is there a brand of basic filters available where every color filters out more or less the same amount of light?

Thanks!
