I had a similar issue that I ran into when I had my aftermarket parts painted.
My paint code is C25 (Chrome Orange) but the high end body shop I was using could only come up with B25 (a different variant than my Chrome Orange). The body shop kept telling me I must have the wrong code. I insisted it was correct. Then, after two unsuccessful attempts at matching my OEM paint, I requested that the body shop contact the paint manufacturer who then sent out a rep to match it correctly (and use the correct code
I asked Andy Graham of Lotus for clarification on this issue and this is what he sent:
"A new paint system, Cromax Pro, which is an activated water based coat, was introduced for specific paint colours in May 2010 as a running change and can be identified by the letter ‘C’ prefix on the paint code, whereas the previous standard Cromax paint was identified with a ‘B’ prefix.
The difference between the standard Cromax and the Cromax Pro is the finished appearance, i.e. the metallic effect of the Cromax Pro system is now applied to the base coat with a standard clear coat, whereas the previous Cromax system the finished effect was achieved through a tinted clear coat over a solid base coat.
The finished appearance for the same colour may vary between the two paint systems, therefore it is essential the correct paint system is used when carrying out paint repairs."
Besides your paperwork, you can also locate and verify your paint code that is printed on the VIN decal that is affixed behind the passenger seat:
"The number is also printed on a label stuck to the vertical face of the fuel tank bay, below the front edge of the right hand rear seat cushion or luggage shelf. Pull back a flap in the carpet to view."
Hopefully this at least explains the difference between your C
114 and B
