workshop: Colors at SHA2017: flag colors on the screen, in print and in paint

RGB vs CMYK, the battle

Event large

The SHA logo and design are based on the SHA hashing algorithm and its colors.
But the colors on your screen differ slightly from the colors on the stickers, booklets, and signs. In this talk, I will give an introduction to the SHA2017 design, to the difference between the color space for a screen and in a print. And I’ll talk how to use this in design, prints, and LEDs.

In this talk, with plenty of room for interaction, I want to explain from a physicist's view about the freedom flag, the SHA2017 color algorithm & design, and why hiding stuff in color codes is a bad idea if you want to distribute other than online.
The first part of this talk will go deeper into the SHA2017 design, the flags, the booklet, stickers, t-shirts, and the LEDs of the badge.
It will also go deeper into the difference between the additive (RGB) and subtractive (CMY) color spaces, and I want to introduce the L*a*b* color space to harmonize between the two systems. It will explain how your eyes fit in these color spaces and what color really is.
