How to correct color in SHO process?

When I add Ha, Sii, Oiii photos (SHO) in RGB combination, the Ha applies in the green tunnel, the Sii applies in the red tunnel, the Oiii applies in the blue tunnel, but the whole final photo is too much in green color, so how can I correct the color of the final photo in siril? Otherwise, I always need to export the final photo and read it into photoshop to correct it, very inconvenient…
