+## Color Coding
+
+Labels may apply to an individual item, a box of items, or the contents of an entire shelf:
+
+- <span style='background: #ffffff; width: 1.6em; height: 0.6em; display: inline-block; border: solid 1px;'></span>
+  **White**: items may be freely used according to common sense.
+- <span style='background: #43A047; width: 1.6em; height: 0.6em; display: inline-block; border: solid 1px;'></span>
+  **Green**: it’s just like white but with the owner’s name so you could contact this person to ask something or bring some sad news.
+- <span style='background: #FDD835; width: 1.6em; height: 0.6em; display: inline-block; border: solid 1px;'></span>
+  **Yellow**: you need permission from the owner or at least a resident to use this thing or anything from the shelf.
+- <span style='background: #E53935; width: 1.6em; height: 0.6em; display: inline-block; border: solid 1px;'></span>
+  **Red**: restricted access. Usually it is an unfinished project or some personal things.
+
+If you have any doubts, please do not hesitate to ask about the status of anything.

+If you want to take something out of the hackspace you must contact the owner or a resident first.
