Hello everyone!

I'm using multiple sources to learn japanese and I've observed some differences from one source to another, which confuses me and I'm not sure which is the right to learn. For example

In one place 'white' is written 'shiro' 白
Another place writes it as 'shiroi' 白い

Pretty much the same with 'kuro' (black) and the words are not used in any context. I'm wondering why this occurs, which form should I learn? Do I read the 'i' or is it silent (I heard it read both with and without the 'i') and do I write the 'i'?

I would appreciate if someone could shed some light on this for me
Thanks in advance!
