This paint scheme is based on the Mason 4-4-0 "Highland Light"
shown here in an original lithograph.

There is still debate as to the exact shades used on the Highland Light,
and if in fact a Mason Bogie ever wore these colors.
but based on Mason color practices, it seems possible. (although not terribly likely in my opinion)
The russia iron boiler in this particular painting should be MUCH darker..it is far too light a grey.
it is shown this way because I based the entire scheme on the 4-4-0 lithograph.
