colour theory - transparency + opacity - lifting + staining characteristics of watercolours

....following Maggie Latham's 5th post on Exploring Colour  I'm posting one of the exercises suggested this month by Maggie   looking at properties and characteristics of watercolour pigments ... a simple exercise to see if colours are transparent (semi transparent) or opaque (semi opaque) to read more see Maggie's excercise 3 .....it seemed a good opportunity to also test lifting and staining properties at the same time on the same sheet  ....inspired by some basic exercises  in  Linda Kemp's  Watercolour Painting Outside the Lines .... at the end I spent some time cross referencing with W&N colour charts and making additional notes of the characteristics of the pigments on the colour swatches ... ... the exercises will make valuable personal references  ..
The excercises are time consuming  but it's interesting to see  which transparent pigments are staining  or non-staining  and which pigments are opaque , semi opaque and or sedimentary .... alot of knowledge is already gained from painting and your own experience but actually making the time to make the tests and charts is invaluable.

...adding a note to my post as I've just finished reading Zoltan Szabo's chapter on Qualities of Transparent Watercolour pigments  "Watercolour Tips and Tricks " ... he explains the properties with great clarity and there are some excellent excercises to follow.

The exercises take time but you learn so much and have it right at your fingertips next time you pick up that tube of color :) And being such a color geek, I love seeing color swatches and tests! Maggie is doing a great service offering her knowledge on her blog for free :)

It is well worth time spent to go through these exercises and really see how colours perform.

It saves time and frustration in the long run for future paintings. And I love the charts of colour. I put mine in a little book and have them to refer to when needed - or to just look at. :)

Wow, Jane!
What a coincidence! I made my own colour chart 2 ago and will upload it next Mon. I felt the need to "know myself =using colours" in order to enjoy washes. Thank you for sharing the info.
Cheers, Sadami

Hi Jane, Gosh these look really awesome!!! so neat. It is amazing how this kind of colour theory work really does help us become better painters. Just the brush work and pigment mixing alone has to be good for us (ol)....
