Hexadecimal numbers (0xXYZ) aren’t recognized by IntelliSense. I thought Lua didn’t support hexadecimal numbers when IntelliSense decided to reject it…
I’m using those numbers to convert string represented hex colors (like 488BC0) to Color3 values. Hexadecimal numbers make a million times more sense than decimal numbers in cases like this or when handling any bit-aligned stuff.
