How do I change the default color cycle for holoviews (for my Panel app)

[Marc]

I can though change the color opts each time I generate a plot via

curve_opts = opts.Curve(line_width=4, responsive=True, color=hv.Cycle(colors.COLOR_CYCLE))
return data.hvplot(x="Datetime", y="Value", by="ElementName").opts(
    curve_opts
)

But I would like to avoid that.
