I the the above needs a bit of clarification.
There is no inherent difference between the TN and IPS (I'm not
sure what you mean by "I-IPS") types in terms of the number of
colors which can be displayed; this is controlled by the panel's
color gamut and the bits/color provided by the panel's column
drivers. Fewer bits/color are typically provided by current TN
panels vs. IPS, just because the TN technology tends to be used
in the lower-cost products (which then also use the less expensive
column drivers) - but don't misinterpret this as a limitation of the
LC mode itself. Response times in the two types are also both
improving, although again the IPS types (and the other leading
"wide-angle" technology, VA) will likely wind up the fastest as
the improvements are coming first in the higher-end panels.
The absolute fastest response to date is coming from yet another
LC mode, "OCB" (optically-compensated bend), which is most
like the TN in its basic operation and manufacturing but not yet
being introduced into the monitor panel market (like the others,
it's really being pushed by the needs of the larger TV panels).
