Description
Default colors aren't matching when using streamribbon(). Also, a warning message is printed.
load wind
[sx,sy,sz] = meshgrid(80,20:10:50,0:5:15);
streamribbon(x,y,z,u,v,w,sx,sy,sz);
fig2plotly(gcf, 'offline', false);
The previous code prints the following warning message:
Estimated Draw Time SlowThe draw time for this plot will be slow for clients without much RAM.
And it does take a lot of time to plot.
Expected and generated (https://chart-studio.plotly.com/~xarico10/1015/#/) plots:

Research direction
Start by running the MATLAB example using streamribbon() and then fig2plotly(gcf, 'offline', false). Compare the expected and generated plots linked in the issue, and inspect the warning and plotting delay. Done means the generated colors match the expected plot and the reported slow-draw behavior is addressed.
