Hello i've gotten myself into a school project and now i'm charge of setting up a color sensor that will detect a skittle's color to make a trapdoor open and it dropping down into it. We are making this project for a small company close to the school and their requirements are that we build it small, maximum size is about 1x1x1 metre and we have to move our skittles with a spiral that can either look like this or this that is my main problem to get the color sensor to work with the moving of our skittles. Here is a picture of the companies actual product this is now a small part of the whole system but it's what i'm going to focus on. I'll give you a link to the whole pdf about their main product so you can see it as a whole but it is going to be in Swedish. Page 2 contains the picture about the product.

I've come across a lot of different color sensors you can you use with an arduino card but all with a very short range and the object it needs to detect should be atleast big enough to cover the 4 led's if now i'm going with a TCS230

I'm sorry for the bad grammar but i'd really appreciate the help. If you have any questions please tell me about it so i can clarify my post. Thanks for reading and hopefully helping me out.

Well...using different coloured LEDs and shining a light on to the skittle and recording the feedback voltage from an LDR would work...

A red skittle will reflect a lot more rd light back than any other...
A blue.....................................blue....................................

etc. etc.
