Hi @Jurassic_P_Ark !
“light” is just the name of the object, you can choose to call it light or sunshine, but in the end, is not more than a cone which can have a yellow colour.
Answering your main question, is there a way to set the lightning of an object, I suggest you this post where people smarter than me talk about it.
Look at this photo, it´s just a flashlight with a yellow “cone frustrum”. What can you do to change a colour of an object? You can set when light collides with the object, set the colour to…, I think it could work.
Hope it helps,
