Brilliance can be created by placing a focal bright object on a background luminance gradient.

Your photoreceptors inhibit their neighbors when stimulated. This enhances detection of line, edge, and contour.

Afterimages, when combined with saccadic motion of the eyes, greatly increase the detection of edge and line.

If it isn't changing, it's disappearing. Troxler Fading is one of the stranger things our visual system does.

Your retina can adjust sensitivity to local conditions
