DIY Painting
I have coppertone Maytags, washer and dryer, and only the dryer has the shading on both the top and front panels. Doing the shading isn't that hard, even for an amateur, but I think the problem would be in getting the right shades of paint -- in cans anyway. I painted my (formerly avacado) GE fridge coppertone. Most brands of spray paint have a 'coppertone' brown which some call "leather", but there was no lighter brown that would have worked, so I did it without the shading. (I think the avocado might be even harder to find). As obsessive as I am to detail, it looks fine.
Spray painting takes a decent amount of skill, some practice, and a lot of patience -- especially if you use the cans. The key to any good paint job is always in the preparation, and for painting metal it's even more critical than for any other surface. The tiniest flaw will show up, not to mention any spec of dust or lint. You have to sand out any rust, 'pock marks', etc., with a fine-grit paper so you don't make a worse mess by making scratches in the surface. The sanding will also etch the surface to help the paint adhere. I have a great airless electric sprayer, but since it's such a drag to clean these up afterwards, I've learned to master the spray can. Getting the knack of spray painting isn't that difficult; the hardest thing for most is finding the right spot to do it -- good lighting, the right temperature & humidity, and no bugs or dust in the air.
I don't mean to sound negative about doing the painting yourself, and I can give you some tips if you'd like -- such as letting that gnat just sit there and die till the paint dries! I just wanted to point out that it's one of those no pain, no gain things. I've grown to love doing it -- so much so that there's a hole in the ozone layer right above my home! My son-in-law is an auto body painter and tells me that the painting is the easier part and that the prep work can be a big variable to the cost. So, if you go that route you might want to tackle that part yourself.
As far as the easiest and least expensive option goes, I think that would be finding another cabinet as you suggested.
