TEMPERING COLOURS.
These are approximations to the low-temperature tempering colours.
(As opposed to the high temperatures as which metal bends or melts.)
It should be possible to print this out and use it for comparison in the workshop. I would be interested in hearing if the colours are correct on different printers etc. All feedback and comments welcomed.
