yellow
The yellow wavelength is relatively long and essentially stimulating. In this case the stimulus is emotional, therefore yellow is the strongest color, psychologically. The right yellow will lift our spirits and our self-esteem; it is the color of confidence and optimism. Too much of it, or the wrong tone in relation to the other tones in a color scheme, can cause self-esteem to plummet, giving rise to fear and anxiety. Our "yellow streak" can surface.
In this photo of a bird, I see the bird, branches, and bricks in the background. The color yellow, can be seen in the bird only. This color conveys a sense of vividness in my opinion. This image is appealing to me because the bird stands out the most.
In this photo of a golden poppy, I see the flower, grass and the golden gate bridge. The color yellow, can be seen in the flower only. This color conveys a sense of vibrancy in my opinion. This image is appealing to me because of the background.
