There's a nice project for a student. Take a DVM with RS-232 port, Visual
Basic or some other similar programming language and make it pop up a big
font resistance value and color code pictorial of a resistor. You tell it
whether the resistor is a 1% or 5% (additional tolerances optional) and
the system does the rest. Personally I just look at the resistor and think
4.7K (or 4K7 if I'm having brioche and/or cappuccino). You just have to
avoid designing in those few values that are confusing.

Best regards.
