[#]sidays #Tubingen

We discussed colors and color use in data Visualizations - is blue 🔵 more or less than red 🎈?

Who of my bubble is here? #kaynieselt and I will catch up later for a biovisevening.

@helenajambor

Uh, let me know if you find an authoritative answer to that one. It’s oddly context-dependent, no? Temperature: red=high, gene expression: red=low?

@leonardblaschek absolutely! We had as many interpretations as participants. Conclusion: colors need to be explicitly explained as not "inherently" clear.

@helenajambor @leonardblaschek And even the context is context dependent — for astronomical temperatures, red = cool (relatively, of course) and blue = hot … so 💯 on the "explicitly explained" approach

@helenajambor In that context, blue (ice) feels a lot cooler than red (fire). So I think it's a good choice.

@helenajambor As a general rule I don't consider colours to have inherent ordinal hierarchy. But some colours in some contexts have semantic meaning (which can be ordinal and hierarchical). Like temperature in your example.

tl;dr don't think of colours as having numerical meaning, but consider their semantic meaning (given context).
