Winsor & Newton
Ten 12 ml tubes of Designers Gouache, from Titanium White to Mars Black, that dry to a smooth, matte flat finish with no brush marks.
Best for: Designers, illustrators and commercial artists new to gouache
The Winsor & Newton Designers Gouache introductory set has ten 12 ml tubes of the brand's Designers Gouache, which the listing says has been popular among designers, illustrators and commercial artists since 1935. Gouache is an opaque water-based paint, so light colors can cover dark ones, unlike watercolor.
It dries to a smooth, matte, flat finish with no brush marks, which reduces light reflection when you photograph your work. The ten colors include process yellow, magenta and cyan plus white and black, a useful base for mixing.
Based on the manufacturer's Amazon listing.
Winsor & Newton says the dried finish reduces light reflection, which makes it suited to photographic reproduction under external lights.
The paint has a thick, sticky consistency that flows steadily from the brush and dries without brush marks, which suits flat areas of color.
The set includes Process Yellow, Process Magenta and Process Cyan with Titanium White and Mars Black, so you can mix a wide range from few tubes.
The listing says Winsor & Newton's Designers Gouache has been popular among designers, illustrators and commercial artists since 1935.
