PCs are no different than any other device, resistors are resistors.
Red yellow yellow would be 240k according to my calculations.

NO. That colour code chart is not complete.

The gold is the multiplier and silver is the tolerance. Odd to have 3
bands for the digits though, that's normally
only on close tolerance parts.

It looks like 24.4 ohms to me.

This is cute ! Check it out.

a fun app.
Interesting the significance of the wide space between band 1 and 2.
In 4 band useage you would normally read the other way around as the space
would be between the multiplyer and the tolerance band
