Saturday Sun and a colourising experiment

I captured these this morning through cirrus cloud. Just as well, it clouded over properly afterwards. I noticed no significant spots in white light, so just some Ha from the ED80.

After a comment about the lack of brightness in my last solar post, I decided to experiment a bit with how I colourise my images. I have traditionally used a levels layer to drop all the blue out, and reduce green output to 150 in order to produce my orange solar images. Today I tried using a hue and saturation layer to colorise.

In both methods black is black, but using my levels layer the brightest pixels are yellow/orange. With the hue and saturation layer, the bightest pixels are white.

Which do you prefer? What looks best? I've also posted the monochrome uncolourised images as well.
