Unit I, Lesson 8--Phthalo Blue Color Chart

Phthalo Blue Color Chart

Phthalo blue is a transparent blue that leans yellow (so it is on the green side).  It is a strong pigment; a little goes a long way.

I feel like I really have this process down pat, so this will be a short post.

Materials needed:

• Oil Colors
• Alizarin Permanent
• Cadmium Red Deep 
• Transparent Oxide Red
• Cadmium Yellow Light 
• Cadmium Lemon 
• Viridian Green 
• Phthalo Blue (lots of it)
• Ultramarine Blue
• Titanium Zinc White
• Canvas pad--I used Centurion oil-primed linen, 9"x12"
• Masking tape--I used 3/4" tape

Unit I, Lesson 8 took me about 2.5 hours to complete.  

Step One: Divide the canvas

Divide your canvas pad using the method outlined in Unit I, Lesson 1.  See my time-saving T-square trick here.

Step Two:  Arrange the colors

The colors remain in the same order as in the first color chart.

Step Three:  Mix the colors and apply the paint

I continued to use my value scale as explained in Lesson 6, here.

Step Four: Remove the tape

For some reason, I had trouble measuring this one.  The last column is wider than the others.  Oh well!
