“Hue” in a name means the color is matched with a cheaper pigment than the traditional one. Amazon’s copy of the older box lists Intense Blue and Emerald Green among the colors, so older stock may differ.
Is Cotman paint good enough for beginners?
Yes for learning and sketching; Winsor & Newton designed Cotman as an affordable line with good transparency and tinting strength. Its manufacturer’s copy on Amazon says costs are kept down by replacing some of the more costly pigments with cheaper alternatives.
The same copy says Cotman has a more uniform consistency than the Professional range, so there is less to learn about each pigment. Cotman colors share hues with Winsor & Newton’s Professional Water Colour, so you can add artist-grade pans later and mix the two.
What else do you need with the set?
Watercolor paper and water; most sketchers also add a water brush. The included travel brush is short, and a water brush such as the Pentel Aquash carries its own water.
Winsor & Newton doesn’t say on its US or UK pages, and Amazon lists the set only as “Imported”. Marketplace listings disagree, naming China, France or the United Kingdom.
Winsor & Newton is a British brand, sold by ColArt, which Amazon lists as the manufacturer (ColArt Americas). Check the box if origin matters to you.
