How to set BackGround color for even and odd rows

[spn13]

How to set color for even and odd rows for filePanelsListFocusedInactiveRowBackgroundColor from the settings interface in theme settings? When choosing a color, only one color is available. You can change it via json, but how to calculate the value for two colors?

These colors are calculated as an alpha-based blend between the primary color and the background color (filePanelsListRegularEvenRowBackgroundColor/filePanelsListRegularOddRowBackgroundColor):
