Cabinet and doors color schemes

[Lost Coz]

Have looked online and found panel and trim colors for the 2022 Solitude 390RK as Brockton Cherry. Confirmed in the parts lookup, but there isn't a touch up pen or wax pen (aka grease pencil) that I can find. There are some close ones but still off.

GD Appears not to offer any touch up tools in accessories or parts so not sure what the techs use? Anyone have ideas on matching touch up pens/wax pens for the Brockton Cherry finish?

Thank you
