The text layer’s stroke color, as an array of [r, g, b] floating-point values. For example, in an 8-bpc project, a red value of 255 would be 1.0, and in a 32-bpc project, an overbright blue value can be something like 3.2.
NOTE: If the text layer has different stroke color settings for each character, this attribute returns the setting for the first character. Also, if you change the value, it resets all characters in the text layer to the specified setting.
Array [r, g, b] of floating-point values; read/write.
