We've had a question regarding the colour acuity targets.
The colours on the colour acuity charts are relatively arbitrary right
now. They are nominally chosen to be Red, Green, Blue, Yellow, Orange,
Black, Grey, and White, to match what's often on hazmat labels but you
should expect to calibrate on examples at the competition. Of course,
lighting colour, shadows, reflections (including coloured reflections),
and so-on will also shift the apparent colour.
There are plans to standardise these colours eventually (they appear
also in our other tests), we're working to find exact shades that
reproduce well on different types of printers and printing services.
Events like RoboCup help us to do that.
Related to this are the hazmat labels, which are as specified in the
standard, US DOT 2009 CFR 49:2. As these are printed artefacts, the
standard uses Pantone colours. Having said that, I would not rely on
this colour definition precisely, both in reality and in the
competition, as there can be variation. In the real world, labels fade
or get dirty, and while there is a standard, there are variations in
printing. In RoboCup, we would hope the labels don't fade or get too
dirty but there will be some variation depending on how they are printed
(even though we do try to print these on calibrated printers where
Examples of printable hazmat labels, complete with Pantone colour
specifications, are available from
. We'll be publishing a list of
labels that we'll be using closer to the competition.
