Map of various Arctic cultures during the Middle Ages
Article(s): Six articles here, tons in other languages
Request: Could either the Dorset or the Norse be recolored so that they're colorblind-understandable? I know my history well enough to know (1) that the Norse controlled Iceland during this time, and (2) that they didn't control anything of the Canadian archipelago; therefore, I can recognise which cultures lived where. However, some areas are ambiguous, and it would be nice to be able to understand the map. Could either the Dorset or the Norse be changed to a deep grey?

Graphist opinion(s):
I changed dorset to be a lighter green, which seems to work for all three common colourblind types. The flood fill missed a few spots, but it should be fairly obvious working out what they are (out of place pixels on the border of a continuous colour). FWIW, GIMP has a 'colour deficiency' filter to approximate what a colourblind person would be able to distinguish (I'm not going to go as far as to say it's what they can see) in View->Display Filters... (Colour Deficient Vision). gringer (talk) —Preceding undated comment added 14:38, 20 September 2010 (UTC).[reply]
That's good to know. I'd like to know WP's consensus on colorblind-adjustment. Please correct me if any of this is wrong: Prot- and Deuter- varieties of color insensitivity are red-green abnormalities that occur in maybe 10% of the population, for which corrective adjustment is very similar. Tritanopia (blue/yellow*), on the other hand, is more like 1 in 10,000 and requires a different type of adjustment. The diminished spectral palette of colorblind-adjusted images has real impacts on comprehension of the other 90%, though a minimal nudge to the slider can allow borders to be distinguished. My feeling is that best practices for WP shouldn consider the first two types as a design consideration, but ignore the third rare third type. Do you concur?

In the two instances of colour deficient correction that I've taken up (this, and a periodic table showing radioactive danger), correcting for all three hasn't been significantly extra effort compared to correcting for just the most common ones. However, I'm not convinced we should consider colourblindness in our design decisions, because doing that in the first place is excessively time consuming for people with normal vision. It would be more helpful to have some colourblind people to peruse these pages to identify tricky images, and it's likely that only the Protanopia and Deuteranopia insensitive versions would get noticed — although I've got no problem if someone with Tritanopia wants to help out as well. gringer (talk) 20:51, 23 September 2010 (UTC)[reply]
To clarify a bit further, I presume that the ideal map colours are colourblind-friendly (it would be great if a colourblind person could please check this to make sure); these colours should be used in all maps, if possible, to establish a consistent look for maps throughout wikipedia. In the particular example here, it would work as a four-colour area map, because there are only four regions. But doing that would be a different matter requiring significantly more effort (and better suited to an SVG map). gringer (talk) 05:20, 25 September 2010 (UTC)[reply]
Please excuse my kibitzing, but it strikes me that a chronological progression should be reflected in the coloration, using either shades & tints of a single hue in order of lightness (or saturation), or hues in spectral order of wavelength (from red to violet or vice versa).

Since there have been no objections and Wereldburger758 is otherwise occupied, I’ve uploaded a new version (see gallery above) with a ‘progressive’ colour scheme. While I was at it I made the following corrections, referring to the original image:
Request: The circuit layout has been modified slightly. Could somebody please update the graphic - or create a new 'current' version. The problem is, that the grey 'cut through' between turn 9 and 11 is different. It now turns immediatly right (where the full (black) circuit turns left) at turn 9 and then left to run straight into the main straight, instead of going straight on and turning right to join the Goddards loop.
Looks about right, thanks, but could you possibly remove the white where you've cleared the old bit and replace it with transparent, otherwise it will look wrong for people who have their background a different colour :) :) - Also, just noticed that "Bridge" has been spelt "Brigge" (not your fault, it was in the original) Could you perchance correct that too :) Guinness (talk) 18:52, 2 November 2010 (UTC)[reply]
Ordnance Survey map that I used as a base. The relevant bit is far right around the vertical centre (north of the Motorway - (blue road) and building marked "University" and to the left of Building marked "Piccadilly Station" (train station)). The building in question has a segment marked "Ct" on this map.
Request: Convert to SVG if possible please. Original is a Paint Shop Pro 7 psp file if this is of more use than PNG. Any other improvements you think are necessary. Pit-yacker (talk) 16:29, 29 October 2010 (UTC)[reply]
Hi! That looks much better thanks! IMHO, the colours are fine as they are. If it isn't too much work then a North orientation would be good please. Thanks again for your work! Pit-yacker (talk) 11:48, 7 November 2010 (UTC)[reply]
Graphist opinion: PDF's are a pain to edit - that's a relatively recent upload, I'll try contacting the uploader directly and see if they'll fix it. Kmusser (talk) 20:15, 8 November 2010 (UTC)[reply]
Request: Could the following countries be added?
Bahrain Viet Nam Ukraine Italy Haiti Laos Singapore Switzerland, as well as the caribbean islands bonaire, Sint Eustatius and Saba (in green)
Ireland (the republic) (blue) Thanks! L.tak (talk) 23:00, 5 November 2010 (UTC)[reply]
Request: I would like to have an SVG image created, with some less... bold colors, maybe just light shading. Source is [1], though I don't see a svg base image, only File:Washington_Locator_Map.PNG... If possible I would like to have it be SVG, but PNG would work too, just something less.. special than the current image. Thanks! Admrboltz (talk) 19:36, 6 November 2010 (UTC)[reply]
