New methods, standards for describing Seven themes admin page

I think most of the inspiration for the wording came from the style guide and the interpretation of Drupal's basic principles into Seven's own principles:

• powerful: confident, precise shapes and strong contrast, especially for user-controllable elements.
• empathetic, responsive: choose calming colors and rounded forms; give emphasis to what matters;
• clear, direct, concise: use crisp lines and simple, decisive shapes; avoid patterns, texture, and ornamentation; each element should serve a clear purpose; make measured use of whitespace: room to breathe, but avoid sterility and emptiness; use rules/boxes sparingly.
• accessible, transparent: appeal to the greatest possible number of people; choose a legible typeface; set text for optimal readability; emphasize what matters; use consistent visual cues for affordances.
• natural: desaturated tones: avoid neon/artificial colors; organic rather than geometric forms; choose a typeface that retains a trace of the human hand.
• friendly, collaborative, democratic, respectful: choose cheerful colours; avoid high contrast at large scales (too bold/aggressive); prefer well-known design patterns, iconography and affordances; avoid visual indulgence, ensure visual style is extensible and flexible.

The objective of the style guide in summary:

• A primarily light tone to appear bright and open
• A neutral, desaturated color palette, both friendly and calming.
• Legible, readable typography. Employs a typeface with some humanist characteristics in a few weights and styles.
• Crisp lines and sufficient contrast, but not jarring. No large areas of bold colour.
• Bold shapes reserved for headings and action elements.
• Some rounded forms to communicate friendliness and naturalness.
• Little or no ornamentation: no patterns, textures, gradients or shadow/emboss effects – except to communicate affordances.
• Borders and background tone as grouping devices only: to clarify relationships and emphasize important elements.
• Generous and consistent use of whitespace.
• Aesthetically appealing, though minimal graphic style; should appeal simple but not sterile; gracious rather than opinionated; confident without overspeaking.

Maybe we aren't fully there in implementation, but they are the objectives.

Updated the description per Jen's suggestion in comment 27 as suggested. Added Alt text and tags as well. Changes are as follows:

description:
  'The default administration theme for Drupal 8 was designed with
  clean lines, simple blocks, and san-serif font to emphasizes the tools and
  tasks at hand.'
alt text:
  'Default administration theme for Drupal 8 with simple blocks and
  clean lines.'
tags: 'multi-column, fluid, responsive, san-serif, accessible'

by way of support ... here is the relevant extract from the log file ... it is quite well hidden

Unable to parse core/themes/seven/seven.info.yml: Unable to parse at     [error]
line 4 (near "'The default administration theme for Drupal 8 was
designed with").

Hope this helps... I am in IRC if you need a nudge in the right direction.

Updated "alt text" indentifier to read "alttext"

Updated patch to remove line endings for descriptions and change arrange key spaces to underscores.

Reverted array key spaces, kept line endings as changed above.

Finally learned to test locally first and not spam the issue queue. Sorry!

re-rolled Holly's patch to correct the spelling of the 'sans-serif' tag. When this is committed to core, please pass attribution to holly.ross.drupal, bladwin, and tedbow [core sprint mentors at DCATX14]

This could either say " to emphasize the tools" or "that emphasizes the tools"

Nothing else apart from that.

Fixed that to "to emphasize the tools".

Thanks Holly! It nicely captures the core focus of the Seven theme :)

The description field seems to have a weird leading quote mark. Otherwise it looks good.

Nice catch.

Looks good. Should come back green :)

Committed 2858a83 and pushed to 8.x. Thanks!

Just a heads up to anyone interested, a newer issue is proposing to remove the 'tags' data because it's not currently being used: #2471619: Remove tags from all core theme.info.yml files
