@ruler Please note that the purpose of changing the Spine Editor settings to Linear blending is to see the colors blended in the same style as in Unity (which is set to Linear color space). If the Spine Editor was set to Gamma space blending, the Spine Editor display is unsuitable as a preview since it will display completely different blending colors. Export and import is unaffected by these settings, as Misaki mentioned above.
What does the scene now look like in the Spine Editor with Linear blending? Also note that only the main viewport will show Linear blending, the Animation Preview window always shows Gamma space blending.
If it still looks very different, could you please share a minimal Unity project which still demonstrates this issue? You can send it as a zip file to contact@esotericsoftware.com, briefly mentioning this forum thread URL so that we know the context. Then we can have a look at it.
