BEWARE - Tinting models with the sliders in the object Panel can be dangerous. It applies a color scale to the model to allow the original texture to be colored by the tint rather then absolutely replaced.
This can affect certain effects that may be rendered on the object. For example: if the red channel is set to 0 it removes all red from the model. This includes the red in the health bar, if the object has one, and renders it black. When the object is damaged then the object will flash black instead of red.
