Hi Elmopuss. Welcome.
If you have lurked here for any length of time you will know where to find the the refreshments. Help yourself.
With regard to colour, it is possibly worth looking at paint charts and you have plenty of choice! (Red from the fruit of the hawthorn bush, yellow or red flowers or dark green foliage.) The Dulux classic hawthorn green is very dark.
A quick search also returned hawthorne yellow
, so I suspect that virtually anything would work.
