The design rules

The cohesion that comes from everything running on the same livery cannot be overstated. That cohesion is something really unique I brought to the role. A judge who taught in three of my courses knew at a glance which course we were talking about based on the color of the materials.

The problem

I wrote shared rules for the slides, binder pages and reference tools so judges could find key information in consistent places and recognize which course a packet belonged to. The same hierarchy carried across faculty sections.

The rules

Label contrast on pavement panels

Sand capitals on a flat pavement panel measure 4.8:1, AA. On a sheened panel, at the light stop, they fall to 4.01:1, under AA.

What it requires

Body text in bone sits under the label.

4.8:1Sand caps on a flat panel.

What it requires

Body text in bone sits under the label.

4.01:1The same caps on a sheened panel, measured at the light stop.

What it requires

Body text in bone sits under the label.

8.99:1Wine-dark ink (#3A0812) on a full sand bar.
