Colour of B&W Developer

[Frostice100]

I did a terrible mistake and developed colour film with Black and White Developer(Kodak D-76).When i put the developer into the tank, it had its transparent colour and when i pured it back into another bottle (where i stored the developer i had already used) it had a yellowish colour.
Today, i went back and checked and it had gone back to it's transparent colour.
I suppose that i can't use this developer but what happened in the colour?
The colour film i used was kodak colourplus 200.

Thanks for your time

The color was possibly sensitizer and anti halation dyes from the film. I accidently shot Provia 400 at EI 50 and decided to cross process it in ECN2 colour negative chemistry. Upon prewashing it the most intense purple coloured water came out of the tank. Quite impressive.

I understand you emptied the stained developer into your developer waste canister. It will be highly alkaline and the dye will simply have been destroyed in that environment.

I use black and white developer in a replenishment regime, which means I always re-use it.
Even with black and white film it pours out of the developing tank with a darker colour than it appears to have once it sits for a while afterwards.
Don't worry too much about the colour.
What type of colour film did you try to develop: colour negative film or colour slide film?
The fact that you have byproducts from colour film in your used developer might decrease the number of films that you can effectively develop with the same quantity - I can't tell you how much of an effect there may be.

The yellow tint should be, like pointed out by @lantau, anti-halation dyes. Fomapan gives a terribly strong green tint that is just that, but I doesn’t go completely away. The developer works OK, even after tinted.

The range of color from antihalation dyes is pretty amazing these days - is it Foma that has that lovely teal-green color?

I misunderstood your initial post. Sorry!

Yes you can reuse it. Those dyes will be there from the next film, anyway.
