Color conversion failure

[nxz-lt]

What is the reason why the color is not carried when I convert GeoJson using mapshaper

Can you give me more information about the problem? A sample dataset would be helpful. Also tell me what conversion you are doing.

I'm going to convert the shp file to GeoJSON, which data contains the color attribute, and I'm going to use it

I'll need an example input Shapefile and output GeoJSON file to help me investigate this issue. Also, what software are you using to make your map? 你可以写中文。
