Comment:

Hello,

A comment for the MWBP guidelines 3.7 Default Delivery Context [1]. Under
Colors it says:

"Web safe.

(A Web safe color is one that has Red/Green/Blue components
chosen only from the values 0, 51, 102, 153, 204, and 255.)"

The definition looks good but usage of the phrase "Web safe" doesn't always
match the definition. Maybe the spec could say "216 colors" instead of Web
safe (the 216 are the 6x6x6 cube that is part of some popular 8-bit video
palettes). Chris Lilley, copied on this mail, may or may not have a moment to
correct me there.

WG Notes: Rough consensus from discussion on Aug 17 http://www.w3.org/2006/08/17-bpwg-minutes seems to indicate that we should simply drop this notion of web safe colors from the DDC, since it doesn't impact the Best Practices in any way. Done in 1z

Resolution: We will drop web-safe colors.
