Fan Casting Warm Place, Warm Lighting in Sort by Tropes

When a work made and largely set in a temperate location sends its characters to a hotter place like a desert or an equatorial country, this will be visually signified by a notably warmer Color Wash (usually in yellow or orange). This is an application of color theory that establishes the new setting as sunny and hot, and in cases of desert settings, dry and dusty. It can also help to enhance the more vibrant warm colors in the new setting, while also altering how cooler colors like blue and green appear for added contrast. Because of the similarity to sepia tones widespread in westerns, or early-to-mid 20th century period pieces, it can also make the setting seem old-timey. However, yellow in particular can evoke feelings of illness and jaundice, so this may have the additional, off-putting effect of "othering" the new setting, making it look poor, dirty, grimy, and polluted, especially if contrasting scenes set in colder locations are colored naturally or with cooler tones.
