7 - Turquoise Watercolour Swatches

There are literally hundreds of artist quality watercolours available from many brands. I have tested many of them and created swatches as seen on the right. The square box is painted into a damp wash at the top to show the colour mixed in water, with more pigment added towards the bottom. The rectangle is painted in a juicy wash to show the mass-tone. The small squares at the bottom of the swatch have the pigment number and characteristics - staining, lightfast rating, granulation and transparency.

Turquoise Watercolours 

There are no PT (pigment turquoise) numbers, so apart from the Primatek mineral colours, turquoise watercolours are made from a single pigment green or blue such as PB16, PB36 or PG50, or a mixture of green and blue pigments, often including the transparent, staining phthalo colours PG7 and PG15. It can be easy to mix the hue but the granulation of Cobalt Turquoise makes it a useful colour to own.

PB16

This beautiful pigment varies a little from more blue to mid turquoise.

Cobalt teal and turquoise Watercolours made from PB28

Cobalt Blue PB28 is usually associated with a mid blue colour. However it also creates an amazing granulating aqua/turquoise colour. PG50 creates an almost identical hue - see below.

Turquoise mixed pigment hues using granulating cobalt and viridian pigments such as PG18, PG19, PB28, PB36, PG50

The granulating pigments will tend to make these colours more granulating and less staining.

Mixed Pigment turquoise watercolours using phthalo pigments PG7, PG36 and PB15 

The phthalo pigments PG7, PG36 and PB15 can be mixed to create gorgeous turquoise hues with ease. They will be staining and non-granulating. Using Ultramarine (PB29) instead of phthalo blue will add a little granulation but if PG7 is included it will still tend to be a staining colour.

These swatches are painted and added as a guide. The intention is show the characteristics of each colour when painted. The colour reproduction is not perfect but hopefully will still be helpful used in conjunction with the manufacturer's website.  Thank you to those of you, from Canada, Sweden, Australia and the USA, who have helped me with this section by sharing your favourite colours. If you notice errors please let me know so I can correct them. If you have artist quality watercolour that are not shown here and want to help me build up this resource, also please let me know :-)
