I was wondering, is the reason for shifting to a warmer value specifically for this lesson, or is it a more general rule about color shading? I thought that values tend to get cooler the less light is applied to them, and warmer as more light is upon them, depending on both the color and the type of light they’re being hit with.

Hey, I've just finished my rendering work. Overall, I'm happy with what I've done, the final look of my shapes manages to make me believe they're 3d shapes. Despite everything I can still see some mistakes but I'm open to more remarks or advice.
