I used to think it as following: there are three classes of objects:
1) numbers, like 10101
2) pure qualia, like redness
3) the tables of correspondence which connects numbers and pure qualia. Red is (10101----redness).
Physiological qualia are lines in the table of correspondence, and they combines both functional part (number) and qualitative part (redness).
The number of possible pure qualia is at first glance is very large and maybe unlimited, but the number of tables of correspondence is much larger as each pure qualia can be attached to any number, and also each table includes all colors—this drives combinatorial explosion.
The nature of qualia is relatively simple—they are just a type of mathematical objects which do not depend of anything except themselves. The real problem is the nature of table of correspondence.
