You can always cheat and use an ohmmeter to measure them ;)

I have one of those - also a book of colour codes :-)

I might resort to the ohmmeter, it's darned hard to tell the red/orange/yellows apart and the green/blues.

Ohmmeter all the way for me, but I'm colour-blind. For theremin building I want an oscilloscope... darn tuning. Which circuit are you using?

This circuit:
http://www.siliconchip.com.au/cms/A_103277/article.html

It came in a kit with the parts.

I'm not colour blind, but the different colours have a very similar quality (tone? hue?) so the red and orange and brown and purple look very similar.
I started trying to identify the resistors by writing down the colour codes on a bit of paper. Then I turned the page and found the parts list included colour codes, so I could cross check them. I got around half the colours wrong!! And that's before I try to decode them...

Is that not the definition of colour blindness? *some* colours are hard to differentiate if they have the same shade?
