System Information
Operating system: Windows-10-10.0.22621-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3080 Laptop GPU/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 528.24

Blender Version
Broken: version: 3.4.1, branch: blender-v3.4-release, commit date: 2022-12-19 17:00, hash: blender/blender@55485cb379
Worked: (newest version of Blender that worked as expected)

Short description of error
When exporting vertex colors in an FBX file, the FBX export module seems to pick only the first color attribute on the list. If the object has multiple color attributes, exporting any of the others seems very difficult since the order of color attributes is not trivial to change.

Please consider exporting the color attribute set as default for render using bpy.ops.geometry.color_attribute_render_set(name='attribute_name') or simply the active color attribute.

Exact steps for others to reproduce the error
Open attached blend file with a cube that has two color attributes, blue 'Color' and red 'Color.001'. Notice that despite selecting or setting Color.001 as render default, only the blue color is exported.

Hi, Prioritize Active Color boolean property is now added in FBX export panel. This will allow you to export selected attribute as default.
see: #104827 / 4c397ede41
