Co-signing the warm/cool primary idea - if you want an easy start the Daniel Smith Essentials 6-tube set or the Van Gogh 12-pan pocket box hit that palette and are easy to find on Amazon. Skip the bundled kits and grab one decent synthetic round brush (size 6–8) instead; it’ll do 90% of what you need. Also, paper matters more than people think: even a budget watercolor pad like Canson XL will give you the flow and lifting you saw in tutorials, unlike notebook paper.
