Without knowing what your level of artistic knowledge is, what you are willing to spend and what brands are available where you live, it’s difficult to give one specific brand.
Three brands that I know are good and widely available are:
Winsor & Newton
White Nights/St Petersburg/Yarka (paints from the same company)
Of these three, Winsor & Newton is the best and most expensive, Yarka is the cheapest, but still decent. They also market sets of 8 and 12 pan sets meant for school children that are surprisingly decent. If you are a total beginner to art theory and cost is an issue, one of these school sets would be my recommendation. If cost isn’t an issue, they would NOT be my recommendation.
There are many other good brands. Daniel Smith is my go-to, but mainly because of their wide selection, which isn’t necessary for a beginner.
