Just to keep it short and sweet.
If I make this:

Will it work as fast and reliably as this?:

Just a note, I plan on using one RGB LED instead of the 4 colors, and how do the lego sensors work? Doesn't look like they flash the different colors like the homemade one. Could i just have all the colors (white) for it to reflect the color back? Also could I just buy the Lego color sensor and make it work with a microcontroller?

Hi,
[...] how do the lego sensors work? Doesn't look like they flash the different colors like the homemade one.
"LEGO sensor uses a RGB LED, and successively shines red, green and blue light on the object. Reflected light is collected by a light sensor sensitive to all wavelength." (http://www.philohome.com/colcomp/cc.html)
Could i just have all the colors (white) for it to reflect the color back?
Yes, if you get a dedicated color sensor chip (plenty to find at TAOS)
Also could I just buy the Lego color sensor and make it work with a microcontroller?
Sure, it seems to just output an analog voltage.

Alright Thanks!
