Doing touch up on playfields, backglass, cabinets, is a real challenge to match the colors, especially for older games with painted (silk-screened art). Rarely will you ever find any of the premixed colors such as in your example to match the colors in an older game, even the black may not look quite right. I have been touching up games for many years and I have over 100 bottles of water based "hobby" paint and it may take me many, many attempts at mixing the paint and matching a color. I guess you would need to be a gifted painter/artist to be really adept at making colors that match. Good lighting is also critical for color matching.
After you apply water-based paint to the playfield you must cover it with a clear hard sealer, which made help hide your touch up or make it more obvious. Always deep clean the playfield before doing any touch ups. Matching paint to a dirty playfield is not a good idea.
Attached is a photo of my Card Whiz playfield. The game was coated with dirt with many areas of missing paint. Spent many hours removing everything from the playfield, cleaning, touch up, reassemble and several coats of Johnson's floor wax.
Good luck.
