Oil paint techniques

 Fred Chaote       Very good on values

He uses a double primary palette and organises darker colours in front

Warms on left  > Cad Yellow.    Cad red light.       Viridian is his warm blue

and cool on right > UMBLUE       A Crimson        Azo yellow

You need to be able to neutralise colours in landscape painting     Fred uses MUD

A warm and a cool mud.  The cool is very close to  Burnt Umber / mixed from Blue Red Yellow

The warm is close to YO   99% yellow  red   Viridian

Uses Liquin to tone canvas  plus Very little paint and rubs it off   A very light colour to tone
