Light Crystal Blue Production numbers?

[Redpointkid13]

Hi all, first time user here. I bought my first Foxbody mustang last April for $1900 as my summer fuel saver daily. It's a 1990 LX convertible with the 2.3 four banger, and it's painted in light crystal blue. (Original paint) I have been wondering about how rare that paint color is on a car like mine since I almost NEVER see it. I've seen production numbers for Light Crystal Blue 5.0 cars in very old forums, but I haven't found anything on the four-cylinder LX models. I figured hopefully someone here may have some answers on this paint colors rarity, and I would greatly appreciate any info!
Attached is a pic of the car. Thanks! -Red

Nice car for $1900.00 is it a fuel injected 4 cylinder? I’m assuming it it based on the year model.
