There may be times when the primary three color logo might be difficult to read clearly or out of budget (t-shirts, mugs, etc.). In those cases, this two color version might be more appropriate and cost effective. When using the two color variant, please refrain from changing the colors. The one color logo variant should be used when placement calls for high contrast. This is the only version of the logo where it is acceptable to change the colors to meet the needs of the design. Whenever possible, continue to use the colors outlined in this document.
