The ASCE logo in any of its forms must appear clear and visible at all times. The ideal background for the colored logo is white. The colored logo may only be placed on a gray background whose value is no more than 25% black. This ensures maximum visibility.
If a white or 25% black background is not possible, the logo should appear in either black or white, whichever option provides maximum legibility and contrast for the logo and signature.
When the background color is blue PMS 286, the ASCE logo should appear in white.
As shown in the examples on this page, a "background" should extend significantly in all directions around the ASCE logo. If it does not, it will appear as if the logo has been enclosed in a shape which is considered incorrect usage.
