Adding Phthalo!


Adding Phthalo

9x8 oil on Black Canvas

Work in Progress.

Artist Note.

A repost.

A more decorative style painting
with a brighter palette.

Artist Note.

This was a demo using

Thalo instead of Ultramarine
Magenta instead of Perm Alizarin.

First, I paint right on the front of 
the clear glass jug 
with my Phthalo blue and then a
bit of the yellow  to make it greener
for another layer in the middle.

Why?...because I didn't
have anything in the right color
large enough to hold the peonies.

A quick block-in

The black canvas
makes it easy to get the value pattern

This is still based on a
limited palette but replacing the
Ultra blue and Alizarin.
REASON?
Sometimes, what you need/want to paint
cannot be managed with just one
limited palette. 
If you are painting near the coast for 
example, the aqua of the water
will need a green/blue.

Lively spring greens have a freshness
which the red in the Ultramarine blue
neutralizes too much. 

To make clear purples the Phthalo needs 
a cooler red than even the Alizarin
 so a substitute
with the Magenta works perfectly.
Here is the limited  palette
for this painting.

Cad Yellow light

Magenta
Phthalo Blue
