i was just asking sometimes i have an object that is glowing. so i use the ambient . i make it more then  1 so that in the reflection materials( car,...) its super bright.
but when you render out the object it doesnt look like the original color.

for example red. normal red. i make it 3. so superbright. it will be brighter on a reflective surface. but the object itself is not rendered as the original color.
