Haohui Mai updated HDFS-5852:
-----------------------------
Attachment: color-rationale.png
Although I'm not an HCI expert at all, but I think it is worthwhile to document
the rationale of how the original colors are chosen.
If you look at the original colors at the HSL space. They have the same hues
(ignoring the rounding), with different values of saturation and light. The
intervals between them are identical to the ones on http://getbootstrap.com
Hue decides the primary color (i.e., green, yellow, orange). Green is chosen
because the color theory suggests that green color gives an impression of
stability and relaxation. Another reason is that from the HCI prospective, cold
color schemes (e.g., green / blue backgrounds + white text) usually have good
visibility on computer screens.
It is usually easy to see some code is better than the other, but it is
subjective and subtle to tell which color is superior. I'm pretty open on what
color schemes should be used in the UI, and I understand everybody has his /
her favorite colors and I fully respect their choices. I sincerely appreciate
putting the time to reasoning about the changes from the HCI prospective so
that the end-users can have the best experience.
