Steps to reproduce

There are two line series, but only one of them is effected by visualMap. I find the other one seems also changes its color in tooltip.

the option is following:

{
  "color": ["#3fb1e3", "#6be6c1", "#626c91", "#a0a7e6", "#33b86c", "#96dee8"],

What is expected?

The two series should be both effected by visualMap.

What is actually happening?

One of the series is not effected by visualMap.
