This is my first puzzle! So: please be kind ;-).

I was watching a CTC video, when I thought: what if different sets of objects in a puzzle must have opposite parity? So, these rules flew from that thought:

Rules

Normal Sudoku rules apply.

Cells with grey circles must contain odd numbers, cells with grey squares must contain even numbers.

Normal arrow rules apply (digits on the arrow must sum up to the digit in the circle of the arrow), but: the circles of both arrows must have opposite parity.

Normal kropki rules apply (digits next to black dots must have a ratio 1:2), and normal thermo rules apply (starting with the bulb, digits along the thermometer must increase in value), but: the totals of the digits of each kropki-dot must have opposite parity from the totals of the digits on each thermometer.

Red cage totals must have opposite parity from green cage totals.

No negative constraints apply.
