Hi @Anubhav Saini! I'll do my best to answer your questions: 1 - It comes down to how much the lighting changes the visibility of the pure, local color. Local color inherently has a temperature to it-- e.g. an orange (fruit)'s bright, warm orange color vs a light blue flower's cool color-- but based on different lighting scenarios, this could either be completely changed or left as is. A strong, direct light source would have much more effect on the local color, moving it towards the lighting's own temperature, vs a soft, diffused lighting scenario where the local color would shine through much more, reflecting its own temperature. If you are thinking of something more specific, do let me know. 2 - Cool light, warm shadows is definitely a possible lighting set-up. It's just not as common as warm light (e.g. natural sunlight), but you can still achieve it using something like artificial lights or in a cloudy/rainy day. 3 - As objects recede into the distance, there's more accumulation of atmosphere in between the objects and our eyes. So in a normal, clear, blue sky scenario, the objects will have more of that blue atmosphere creating a semi-transparent filter in front of them, causing that cooler effect. 4 - How the light affects the image depends on the scenario's specifics, such as the light's intensity and placement. If the yellow light is small, direct, and strong, it will affect the specific area it hits the most, but the light rays can bounce off that area and onto other nearby objects, and they will fade out as they continue to lose energy. If the light is direct but not strong, you will see most of the light only in the area directly hit by the light, as there is not much leftover energy for the rays to bounce off. In a scenario where the yellow light reaches the entire setting, it still may not show up as strongly in the shadows, if it's so soft that there is little energy for the rays to bounce in the shadow area-- but again, if the light is strong, you will see more of the yellow light rays bouncing into the regions not hit directly by light, e.g. the shadows. It definitely helps to think about the physical movement of the light rays coming from the light source to plan out your lighting scenarios. I highly recommend picking up James Gurney's Color and Light book, as it's a favorite essential guide on color, and I also recommend checking out Marco Bucci's comprehensive videos on the topic as another great resource not to miss, like The Color Survival Guide.
