[scikit-image] New logo?

Hi, everyone It's been bothering me for a while that we have a logo that is not colorblind friendly. E.g., try running scikit-image.org through https://www.toptal.com/designers/colorfilter :/ *I challenge you to submit a new logo, and a hexagonal sticker [0] that we can print for SciPy 2017.** * I will print and ship stickers of the (community) chosen design to anyone who contributes a design of their own. Fire up Inkscape [1], and let's see you work your magic! Stéfan [0] http://hexb.in/sticker.html [1] https://github.com/terinjokes/StickerConstructorSpec/blob/master/assets/hexa...
