colour detecting sensors

[mohit sharma]

Is there any kind of sensors which can be used for colour detection ? If there is so how they can be interfaced with microcontroller ?

when i think of color sensors, two spring to mind.
1. cameras, these are generally more for advanced users http://www.societyofrobots.com/programming_computer_vision_tutorial.shtml
2. the simple photoresistor setup, this setup is easy as pie...
you simply turn one color led on, read photoresistor, turn it off and repeat with a different color led.

Hi,

Yes, quite a few. Taos Inc makes some (http://www.taosinc.com/productfamily.aspx?sel=cs) and you can build from the ground up with a RGB LED.
