Nice picture.
The CLS filter blocks yellow color out completely, hence the bluish tinge.
But there are several ways to compensate it.
In PS you can make a color balance adjustment layer, with balancing cyan to red, magenta to green and yellow to blue.
And another option is using the hue/saturation adjustment layer with which you can tweak the hue, saturation and brightness of each color.
Do this in the final image, i.e. after stacking.
Or use the 'lonelyspeck' method with Photoshop. Some more work, but works very good, last week I did it with my Vela Supernovan Remnant image.
