Trouble is the early Honda colours had no standard make up plus a lot of them were 3 pack "Candies"
the only people i know that do paint that works in this country is RS in bradford, uually advertise in classic bike BUT ensure you are sat down before you ask the price PLUS you need the full airflow mask to use it
just a quick heads up, ASH the HONDA CB250'S i am sure they did not come in candy colours at least not the ones you mention, (red/white and green/white) my friend has a 1970 green/white one (i will try and find out the exact colour as its all original),and i have not seen a red one in years ,strangely enough they did do a candy gold/white k2 which was my pride and joy when i was sixteen
