Thanks a lot.Welcome to AAC!
Look for a sensor that converts light intensity to voltage. For example, you could shine a red light on your white and black objects and measure the intensity of the reflected light.

I am trying to satisfy my curiosity but thanks anyways.You really need to use a micro I think, like an Arduino. It just makes it so much easier to alter settings for instance.
Have you looked at these?

But I suppose you could use 3 x photo detectors of some sort, and colour filters then run the outputs into comparators to generate signals to do the sorting.
An Arduino will be much better!
TAOS (now owned by AMS) has a line of color sensors as well. https://ams.com/color-sensors You could do a light-color to frequency converter -- and then go gonzo from there.Welcome to AAC!

OP knew it could be done with microcontrollers, presumably using light-to-frequency or I2C converters, but wanted to know if it could be done without coding.But the bigger question is -- why are these restrictions placed on the project?
I know we can sort colors by coding an Arduino or a microcontroller. I wonder how can we design a circuit for sorting colors as we want to without coding? For example:
If sensor senses black do stuff and if sensor senses white do stuff.
I guess if you set things up right you could set things up where different frequencies would give different outputs like a DTMF Decoder. There is likely a dozen other ways to go about it using common discreet components.If sensor senses black do stuff and if sensor senses white do stuff.
