Mean ORC 14 and 15

A couple with diagonal clues:

Meandoku (strictly extra) The following colour clues apply:
Green: the sum of the two adjacent cells is 8 or 9 only
Blue: the sum of the two adjacent cells is ten
Red: the sum of the two adjacent cells is 11 or 12 only
Yellow: the sum of the two cells is below eight
Black: the sum of the two cells is above twelve

Odd Row and Column - ORC - so it is:
ORC: odd rows and columns are 1-9 no repeat; even ones are not (i.e. they can repeat).
NN: no nonets

For all cells:
AK: Anti-King - diagonally adjacent are not equal
FNC: Ferz Non-concecutive - diagonally adjacent are not consecutive
NC: adjacent cells are not consecutive

I solve these in JSudoku control-right click allows you to remove the row and column constraints. Note recursively solve works but deduce a move is flawed.

I would be grateful for your views on difficulty.

This one is quite interesting. Note where there is a red block on the corner it means that both the crossing diagonals are red i.e. they both sum to 11 or 12.
I've just gone through the combinations again and realised I missed some; not allowing for repeats on even columns. I've added a clue to make it solvable. However it is hard.
