Using a table normally is faster, especially if you want to access values by
index (that is, not sequentially). You can do some optimizations, too:
For one, you can get rid of one counter, if you send the RGB-list to:

[list]
|
[list split 3]
|
[unpack 0 0 0]
|     |      |
... put to tables

Even faster probably is using just one table for all RGB values: Just
do a [list prepend 0] after [pix dump] and send the 0-prepended list
to a sender with your table-name as target.

You can still access the individual R, G, or B values by adjusting
your index into [tabread] accordingly (use: 3*index + X with X = 0, 1
or 2)
