First what I did was to go through the google art collections and choose paintings that were very dominantly blue. This is not as easy as it sounds, as I had to decide which hue of blue I wanted, some blues were too teal, or green but it would trick my eye into thinking it belonged. After I chose all my paintings and started working on my gallery I deleted several paintings. After seeing them next to each other it was much more obvious as to who belonged and who didn't. Only three of my paintings really juxtaposed the complimentary color to make the blue pop out. These are: Ladies at the Seaside, the women are almost orange in color with red mixed in to their accesories and skin tone. This makes the blue stand out even more. The Cathedral has red added into the bottom which makes the blue much richer. Finally, the Annunciation has pink curtains and drapery, which makes what would be a dull blue stand out much more. I have many great examples of simultaneous contrasts. I could name hundreds that I see but I will pick the most dominant ones. In Contesse d'Haussonville, she wears a light blue dress against a dark blue table and even her reflection is a darker blue. It makes the light dance off the dress so much more vibrantly and makes the Contesse stand out that much more. i think Burg Scharfenberg at Night is a great example as well. The sky and the shadows on the castle are all blue tones I do not think there is one spot where blue is not used at all. However with such contrast in the values it makes it look almost white. I see this where the light hits the castle, In the clouds at the top left corner, and where the light hits the water. They are still blue, but with the deep, dark blue, it looks white. I didn't focus on saturation or value, I wanted these to be different, but I feel my paintings all share the same tonal quality which is why I was able to get rid of some pieces that were blue but not the same tone.
