What is the difference between mazda paint codes?

Im wanting to get the spoiler on my mazda repainted and I looked up the paint color code. My car is 26a (Glacier silver metallic) but there is also a 30a which is just silver metallic. I need to know what the difference is. I was quoted two different prices. One for regular paint and one for pearl paint. So I need to know the difference so I know what I need to expect to pay. Help!|||Pretty self-explanatory in my opinion. If it's not the same paint code, it's a different paint. It will not match. Duh
