please help me in giving a proposal in line with a color recognizing robot. the robot can recognize up to two colors only. any idea what to propose? the theme is "robotics with color recognition."

Jeaniel is closest to the way we do it in hobby robotics.
In a normal line following robot there is an LED (often infrared) and a photo-transistor to pick op reflection.
When color recognition is used either there are two LED's used of different colors (if the target colors match the red, amber, green or blue) that you can get LEDs in.
If those aren't the colors you need then we use a bright white LED and put color filter plastic over 2 or more photo-transistors. so if the LED is shining on a blue surface the majority of reflected light is blue and will only pass through a blue filter.
Those systems are chosen because they're cheap. If you have money and a powerful processor then a web cam is often dedicated to the project and the micro controller can determine the predominant color as a Red/Green/Blue scale, similar to html color codes.

Check out the capabilities of the Lego NXT. They have color recognition capabilities with a sensor.

it seems like you could do something with red and blue. shine a red laser onto red and you'll get more energy back than shining red onto blue.
