Hey, as someone who's been dabbling in acrylics for a bit now, I'd say go for paints that are labeled as student quality because they're usually cheaper and still decent for starting out.
You want ones with a good range of colors that stay bright when you mix them, especially for those landscape scenes with all the greens and blues.
Check the consistency too, something not too thick or runny so it blends smoothly on your canvas.
And don't forget to read reviews from other beginners to see how the colors hold up over time.
Works great for avoiding disappointments early on.
