Often when I start a watercolor painting I try to work on a color.  Yellow has always been a challenging color for me to paint with.  I learned all yellows are not created equally.  That helped a lot.

These are the yellows I have in my palette:

Lemon Yellow-  a cool green yellow.

Hanza Yellow Light - a cool green yellow. 

Arylide yellow - a cool green yellow

Transparent Yellow- mid temp and more orange yellow.

New Gamboge- a warm, orange yellow.

Arylide yellow deep- a warm, orange yellow.

If you don't know which way the yellow you are using leans ( green or orange), you can mix it with a green blue - cerulean.  If the green is bright and clear then you have a yellow that leans green.  If the green you get is a little dull or gray green, then you have a yellow that leans orange.  It's helpful to know this. It will help alot when you are mixing colors. 

Here are some watercolor paintings I created to practice and learn my yellows. In the process I also learned how to use their compliments for shadows ect., I hope this inspires you to create some paintings with yellow. It's such a cheery, warm color.  Thanks for reading,
