A note for the marketing committee, those working on the Logo. I got my samples back from Vistaprint. I have been assuming that the Ardupilot logo would be on a black background, like on the home page. Mission Planner has the Green on Black theme. It seems to be the most common combination for the brand of Ardupilot.
With Vistaprint, and I am sure others will have the same requirement, you need to supply camera ready artwork. There is no clear background to the logo art. So if you want to put the Ardupilot logo on a black hoodie you need to have the logo a rectangle with a black background and the graphic art any color you want.
The problem with my samples is that the “d-max”, a photography term relating to the “blackness” of black, is different for the logo background and the fabric of the hoodie. So instead of the Ardupilot graphics looking like they alone are applied to the fabric, the black background shows up as a rectangle of a different shade of black or dark grey.
On the ceramic mug the black is darker and matches the handle of the cup but on all the fabric based sample or the mouse pad it looks bad to not have the fabric and the logo background match or in otherwords disappear into the fabric.
So just a note that you might want to take this issue into account when you decide on the colors of the logo and their background. I suspect this could be a problem with any colors chosen though. You can actually see it in the Vistaprint mockup of the mousepad above.
PS>> Other people I have shown it too recognize the problem but don’t thing it is a show stopper. In fact it may be a lesser problem with black rather than trying to match a shade of green or red etc where you have to match the color not just the intensity.
