We examined color preference between cyan and green backgrounds, and white or yellow backgrounds. Cyan is a combination of green and blue at their highest intensities, while green is one of the primary colors in the RGB color model. Since we used a darker morph of crab spider for the cyan versus green trials, we hypothesized that the spider would prefer the green background.
White is a combination of the three primary colors at their highest intensities, while yellow is made with red and green at their highest intensity. Since we used a white morph of crab spider for the white versus yellow trials, we hypothesized that the spider would prefer the white background.
