Honestly I like the Krylon blue a LOT better. The Suzuki blue is kinda off looking. Looks almost like it has a green tint to it

Pink and white!! Not enough unique 250's around!! Mine is probably gunna go pink and white and neon green this winter

OR primer grey and unpolished aluminum.

I got the frame, bumpers, engine mount spacers, and rear hubs done in blue by Liberty Powdercoating here in Michigan. IDENTICAL to 19F Champion Blue. Not even a little off. The color code is RAL 5017.

I did an entire frame in RAL 5017 and it looked so bad I had it redone in RAL 5010.  Look through the build pics link in my signature to see some examples. 

The best advice I can give you is to have the powercoater do a sample part before you commit to the color.  I hated the way 5017 looked!

If you like Krylon True Blue, RAL 5010 is the powdercoat code to use.  The Krylon color is very very close to the original blue on the main tube of my 250 under the tank.  That is as original as you can get.  I have owned it since it was new and it has never been repainted or exposed to the weather.

I'm wondering if the bluish green color on some OEM frames (I have seen it) is a result of UV damage on bikes that have sat out in the sun.

That engine looks really nice.
