Choose color of line series

[lp177]

Hi,

I want to create plots with add_line_series where lines can take specific color in certain conditions like threshold of y value.
I have split my lines in sub lines for each change of color, but I want to choose color for each and not let dpg choose a random color for each sub line, is it possible ?

I may have misunderstood but it seems to me that theme feature apply at plot level and not by line.
Can probably do something with draw_line but I think that I'm go to lost datetime features and/or something else ? (this function seems less intuitive for my project so I prefer to ask your opinion)
