Here is the code:
[[0,[159,185,191,255]],
[0.5,[48,157,185,255]],
[1,[56,104,191,255]],
[1.6,[86,90,197,256]],
[1.61,[231,132,35,256]],
[1.80,[231,132,35,256]],
[1.81,[200,66,13,256]],
[2.40,[200,66,13,256]],
[2.50,[215,0,50,256]],
[5,[175,80,136,255]],
[10,[175,80,136,255]],
[17,[154,48,151,255]]]
I guess you know how to use it. But if necessary here are the main steps:
In windy.com Menu (not in the phone app) go to Settings
Scroll down and choose Customize color scale
In Select overlay: Choose Waves
At bottom of page find the line Import/export
Click on [view code] to open a window pop up
Delete the text code in this window
Select and copy all lines of code here below and paste them in the window
Press [Import]
Press Save
These new colors will be saved in your Windy cloud and be applied to all your devices including in phone app.
But if you want to come back to Windy default colors you can press Load default
To you remark ‘ Now, when I try incremental feet it reverts to whole feet’, I would recommend to use meters instead of feet as feet are automatically rounded by Windy.
Then using this color scale, you know that the orange color means wave between 5.3ft to 5.9ft and red more than 5.9ft. That should meet your requirements?
