Haohui Mai commented on HDFS-5852:
----------------------------------
(Disclaimer: I'm not an HCI expert, so please see the comments where it fits.)
As I have said, the preferences of colors are highly subjective. Every people
have their own interpretations of colors. It is understandable that people
(especially software engineers like us) associate a particular color to the
logos they see everyday.
However, I suspect that the end-users (which are a much wider audiences)
generally share the same interpretations as we had here. Therefore, if I had to
choose some color for the UI I would start with two things in mind:
# The impressions of the colors of general populations, which are throughly
studied in arts and architectures for centuries (e.g., green -> stability, red
-> attacking, orange -> hot)
# The color intervals chosen by one of the most popular front-end framework
(i.e. bootstrap). The theory behind it has been quantitively studied for about
50 years \[1\].
After that you'll need to balance the style, visibility, etc.
The original color is chosen to balance the visibility of the texts and the
dropdown icon. Both of them can have two different colors with different
lightness. The color harmony for all these cases \[2\] is achieved only through
multiple trails. What I have learned so far is that the subtle issues do matter
-- therefore I respect the ones that can get the issues right (like Bootstrap)
and follow their leads.
As I have said, I understand everybody has his / her own favorite color. My
focus here is to promote the reasoning behind the choices. I'm pretty open to
the color schemes for the UI. I'm okay on changing the color if someone raises
the concern that the colors can be misinterpreted -- as long as the choice that
has been well thought through.
Picking the politically correct color, however, is not my focus and I sincerely
believe that it should not be the focus of this jira either.

> The HDFS UI colors are too close to HWX green.
> Here is a patch that steers clear of vendor colors.
> I made it a blocker thinking this something we'd want to fix before we
> release apache hadoop 2.3.0.
