Currently, when modifying the penColor-prop, it affects all existing paths.

[MQMMax]

please Set a parameter to control whether all paths take effect

@MQMMax did you ever find a workaround for this?

Define a ref to VPerfectSignature component and after change the color, trigger this:

this.$nextTick(() => {
    this.$refs.signaturePad.inputPointsHandler()
})
