Matt,

thanks for your comments,

You rather bluntly state that SVG allows the user to control the colour 
experience.
Can you please point to the exact method you are refering to?
This is a very complex field, it could for instance be possible to 
high-light moving objects, exaggerate distance fogging, or numerous 
other techniques.
The point is that whereas with text we have discovered some effects 
which benefit some users, very little is being discussed about color 
other than colour contrast (usually with regard to text and background), 
which is a crude tool to weald.

My concern is to ensure that issues regarding these other technologies 
are discussed openly.
I have written to Chaals, asking if it would be appropriate for me to 
join PFWG, and have communicated my concerns regarding SVG and the way 
it is developing, on a regular basis.

In particular I am concerned that for the present vectors do not seem to 
capture human faces well. though there is a project which has 
specifically this purpose. jpegs are far more efficient, but do not have 
an alpha channel. the combination of svg with jpg is inefficient, 
requiring an extra plugin, and one looses many advantages, such as 
excellent user controlled scaling provided by css.
