The Google has specified an official color for Its Android mascot: #A4C639.
When Karl Ostmo submitted AndroidRobot to the Object Collection, he included the
official color in a comment, but used MediumSpringGreen in production.  He did
not explain the discrepancy, but my best guess is that his linear conversion of
#A4C639 didn't look very official when rendered.

I resubmitted AndroidRobot with the official color last July, but applied gamma
correction to the color under the ASSumption that normal people set
assumed_gamma 1.  The other day, recalling last September's epic arguments in
povray.advanced-users, and still somewhat convinced that Warp is a normal
person, I decided that my ASSumption was inappropriate, and added the
uncorrected color as an option.  To assess the different religious views, I ran
a test scene with three variables:
  - the POV #version
  - assumed_gamma
  - the official color with and without gamma correction.

The new sRGB feature in 3.7 gives interesting results.  When assumed_gamma is
2.2, the sRGB looks the same as the uncorrected color.  When assumed_gamma is
greater than 2.2 (not shown in the attachment), the sRGB is /lighter/ than the
uncorrected color.

Notes:

  - All 8 frames were rendered with 3.7 RC6.  The version behavior was
    controlled with #version statements.

  - I used radiosity and left the finish { diffuse } at its default
    value.

  - For easy visual comparisons, the border color is literally #A4C639.

  - I initially tried omitting assumed_gamma as an uncorrected control.
    However, this caused a parse error in frames 5 and 6, due to the way
    androidrobot.inc computes the colors, so I used assumed_gamma 2.2 as
    the control.

  - The colored balls are linear conversions of #FF0000, #FF8000,
    #FFFF00, #008000, #0000FF, and #800080, respectively.

  - Pay close attention to the hues of the orange balls.  Orange is the
    only one of the colors with differential values between channels.

  - The green and purple use fractional values, but there is no
    differential between channels.  The result is differing lightness
    values, but no differences in hue.

The Google wishes to remind you that the robot is based on work created and
shared by the Android Open Source Project and used according to terms described
in the CC-BY-2.5 license.
