This question already has an answer here:
The difference between the number of answers and a question with an accepted answer should be clearer on MSO.
MSO vs Cooking.SE
Edit This could be an issue for Daltonics. In my case, I have the brightness of the monitor down to reduce fatigue and the yellow doesn't come out so bright. There are a number of ways to address this. 1. Remove the square from the non-accepted answers 2. Make the square of the accepted answers another form (a star!) 3. Make the square of the accepted answer greener (and remove the yellow letters for contrast). 4. etc.
Edit The real issue (if there is one) is that the difference is one-dimensional, while it should be multi-dimensional. But don't take my word for it.
- Avoid absolute judgment limits. Do not ask the user to determine the level of a variable on the basis of a single sensory variable (e.g. color, size, loudness). These sensory variables can contain many possible levels.
