1. A head-up display for displaying graphics upon a windscreen of a vehicle, the head-up display comprising:
a graphic projection module for generating one or more graphic images upon the windscreen of the vehicle;
a forward-facing camera collecting image data representative of a view of a surrounding environment of the vehicle visible through the windscreen;
an ambient light sensor detecting a level of ambient light present in the surrounding environment of the vehicle; and
one or more controllers in electronic communication with the graphic projection module, the forward-facing camera, and the ambient light sensor, wherein the one or more controllers executes instructions to:
monitor the image data from the forward-facing camera until determining an object of interest is visible through the windscreen based on the image data;
in response to determining the object of interest is visible through the windscreen, determine one or more graphic images to be shown upon the windscreen to bring the object of interest to the attention of a user;
determine the level of ambient light present in the surrounding environment of the vehicle based on an ambient light signal received from the ambient light sensor; and
adjust a saturation level of one or more colors of the one or more graphic images generated by the graphic projection module based on the level of ambient light present in the surrounding environment, wherein adjusting the saturation level of the one or more colors of the one or more graphic images includes increasing the saturation level as the level of ambient light decreases and decreasing the saturation level as the level of ambient light increases.
