Given that the Canadian flag is red and white, that kind of colorblindness is unpatriotic, isn't it?
The hot water technique works, but you pretty much have to completely remove the cover to use the technique properly.
This gizmo looks interesting…

Basically it's a scale that is shaped to fit the base of the cylinder, with a digital gauge that can be mounted outside the enclosure, so you can weigh your propane cylinder without even opening the cover. Downside is that it only works with 20# cylinders, not the larger cylinders typically found on trailers.
There are stick-on gauges, if your colorblindness can tell the difference between yellow and orange, that work for any-size cylinder:

They work on the same principle as the hot water test; the chemical in the indicator strip is temperature-sensitive, and the colder liquid propane turns the chemical yellow, warmer temperatures turn it orange. Downside is you have to be able to see the side of the cylinder so you have to completely remove the cover to use the strips.
