I intended to use R/V/B leds (the addition of an IR one is a good idea) with
an RCX controlled cycling mechanism to light the object under test, and a
Lego light sensor (with it's red led masked) to read the info.

Hi Philo and color light sensor interested people:

I know that Mike Gasperi has designed an unexpensive super color-sensor
based on an input-multiplexer which is driven by switching the RCX from
passive to active sensor-mode all the time. The information is passed
through analog switches. Mike has published this recently in an article. You
should ask him. He also has a ready for soldering PCBoard for this sensor.
And it works well!

Otherwise, I recommend Robolab 2.5 with the Lego Camera or like JP Brown in
his Rubik's Cube solver, the Logitech-camera-package. We are experimenting
with the Camera-feature of Robolab 2.5 and we are really amazed what you can
do with it. Some pages will follow during the next months at our site.
