For a project I designed using blender + Krita this tile:

I also, separately, designed a laser:

However, I want to use the more saturated tile version, and put on top the laser. So I saved the laser with a transparent background as EXR (png format does not handle "emit" light since it does not use premultiplied alpha) [here][3], and I tried to combine them in a new blender instance, in the compositor:

However as you can see, the laser is fine, but the tile is way less saturated. If I change the profile to "standard" now, it's the other way around: the tile is fine, but the laser is wayy too saturated:

How could I properly combine a sRGB image and a linear EXR file?
