Hi all,
Thanks for the feedback. I have tested some other shades:

Any additional comments are very welcome.

Hi All,

Recently landuse=farmland (or simply landuse=farm) has been added to
fields near me. This has led to a discussion about how the rendering
'looks' with some arguing that it doesn't look that good. I believe that
this may be due to the shade of colour used – specifically the farmland
'brown' is not as luminous as the default 'grey' (actually I think it
'lightness' rather than 'luminosity' that matters to the human eye but I
got very confused when searching the two).
Consider the image below, showing current rendering:
https://docs.google.com/open?id=0B6J5ZA1hu93bZDBTN2dZZkpDenc
On the left we have farmland tagged. The 'brown' has a Lightness value of
83 percent (luminance of 85%). Compare this to the default canvas 'grey',
which has 93 percent Lightness (and 93 percent luminance).
Now consider the following (and please check your screen calibration at
http://www.photofriday.com/calibrate.php ). I have taken the farmland
'brown' and raised it's Lightness to the same 93 percent as the default
'grey' (that is, I have left the Hue and Saturation the same):

In this final image, I have adjusted the Hue and Saturation to provide
more of a 'green':

What are your thoughts? Which do you prefer? Have I gone too 'light' with
the change and should some value in-between be used instead? Am I barking
up the wrong tree?
Regards,
Rob
Note: To focus discussion I want to avoid the argument that some people
see farmland as the default and therefore it does not need to be tagged –
it is a legitimate land-use tag and if people want to tag it then let them.
