Rules

Normal sudoku rules apply.

Kropki: Digits in cells separated by a black dot have a 1:2 ratio (ie one digit will be double the other).

Parity Thermometers: Thermometers see only one parity. Blue ones see even digits, orange ones see odd digits.
On a thermometer, digits of the seen parity must strictly increase from the bulb end and must also be strictly dominant. Digits of the unseen parity are unaffected by the thermometer.
Bulb-to-end examples:
Valid blue thermo: 2-5-6-1-8
Valid orange thermo: 3-4-5-4-7-9
Invalid of either colour: 1-2-3-4 (no majority)
