Yellow Ochre v. Raw Sienna
Greys skies: rather than reach for the Paynes Grey
or add water to one of the blacks (as I did in
my school days) I prefer to mix my own greys, putting together a
variety of blues with browns, reds (such as alizarin crimson and
permanent rose) and earth yellows.
With so many greys in the sky this sounds bewildering but I find
that if I take my best guess when I mix the grey, when I start painting
I soon realise that I need just a spot more blue, or yellow etc.
Cerulean Blue, a 'sky blue' - azure - very slightly
turquoise, isn't a 'must have' colour and I don't carry it in my
smaller paintbox but it is useful to have for subjects like this.
For years I've gone for a very limited range of colours but I feel
I might start working with a larger range again.
Yellow ochre and raw sienna are
all but identical in colour but I'm beginning to go over to raw
sienna from the yellow ochre that I've always carried in my box.
Raw sienna is more transparent in a wash than yellow ochre and I
think it is easier to get a smooth wash with it.
I painted the two swatches by mixing each colour, applying a brushstroke
on the left then adding more water to the pool of colour on my palette
and continuing the swatch to the left, finally adding more water
so that with the third brushstroke the colour fades off to the right.
