Transfer color from one layer to another.

I have created a high res stacked image of the last full moon by stacking 30 images: 

When the blood moon happened I took a noiser shot with a much higher ISO: 

How can I transfer the color of my second shot to the first? 

I have used the luminosity layer mode on the second shot but the results are don't look very nice.

Use frequency separation to split both layers into texture and color tones. Then swap the texture layer of the b&w image with the color image.

This would have been better with a higher res file.
