The reason for this update is that I didn't like the arbitrary "difficulty" categories in the old one, and it wasn't quite as comprehensive as I would've liked. This new one splits everything into utility categories instead, so (for example) if you want to do something cool with backgrounds, everything you need for backgrounds is in one section. Items in each category are organised by subjective "difficulty", so don't worry if you can't master everything in a single section at once. Also, there's still a basics section if you're just starting out!
For everything that involves colours, there are 3 recommended options available to you that work for every case here, unless otherwise stated: hex colours (e.g.
#FF0000), colour names (e.g.
red), and RGBA (e.g.
rgba(255, 0, 0, 1.0)). A full list of colour names can be found here (alongside hex values for said colours), for hex I recommend the website color-hex.com (there's a colour picker at the top of the page), and for RGBA there's this tool which should give you what you want.
