[IxDA Discuss] Amber and Yellow color perception

[pauric]

Sorry Jeff, you are right it is easy to tell the difference between a
flashing and solid LED.  However I think what was being proposed was to have
a solid yellow and flashing amber LED.

The blinking state is generally a transient or dependent state of the
'solid' state
In your example, solid red means stop.  Flashing red means stop and proceed.
We use flashing green power LED for booting and solid for booted.

For all intent and purposes flashing amber will look like flashing yellow.
Viewers will assume the flashing amber LED is trying to tell them something
based upon the solid yellow LED state.

So, the most we get out of a single LED are 3 states; off, flashing & on.
We used to have varying states of flashing but again back to the matrix of
possible states and difficulty in interpreting them.

Although we dont use amber & yellow together, I would fully expect to see
users assume that the meaning of those two LED is related.  With the Amber
being associated with a fault as they generally look kind of redish.
