I apologize, I’ve missed earlier discussions so maybe my comments below were already answered. Am I right that the question isn’t which color scheme is better, but instead which is better as a default? If so, that should be driven by market and metrics. Specifically:
- Who’s the design for?
- What does “better” mean?
- How do we know it’s better?
If both options will meet the same level of accessability (the market in this case being “the most people”–a difficult market choice), then “better” is being measured by votes from a specific subset of users. That is, your users who are in the forum and care enough to vote. They’re a particular market. Are they the right one? Since other colors aren’t in the choices, I assume blue is also a branding choice.
What I’m getting at is that people who open the app the first time and don’t like the colors will want to change theme. How easy is that? If one of Joplin’s missions is “notetaking that works for you,” can theme choices more obviously support that philosophy?
For example, there are a bunch of common themes in this arena today that come from something of a standard, e.g Solarized). What if Joplin users create and promote themes that are named for the problems they solve (and markets they address)?
- Red-Green Blind
- Blue-Yellow Blind
- Gray Galore
- Low Light Designers
- Outdoor Journalers
It would be interesting to capture–with permission–what themes users choose and use most of the time. That’s going to tell you what your users really think.
