What are the significance of the colors on the forecast chart.

@idefix37 please send me code for the scale. Also, what increments can I put in the wave height scale. Now, when I try incremental feet it reverts to whole feet.

@idefix37 also, Windy will not let me change the steps, for example it will not allow 4.5 feet, it switches back to 4

@idefix37 I have customized the colors but it is impossible to judge color gradients to discern an useable measurement.

I live in El Salvador. The ocean entrance into our port is over an often breaking sandbar. For ten years, I used the detailed wave forecast on Buoyweather to inform boaters if it is safe to cross the sandbar. but, BW is eliminating that feature. I am struggling with the Windy wave feature because it is in whole feet increments. For example, the bar may be safe with a swell of, 5.2 feet but not 5.9 feet. I've tried working with the color scale but, it is impossible to judge color gradients to discern an useable measurement.
I believe there must be some numerical data associated with the color scale that might be extracted by Windy engineers.
This is a very worrisome situation for me because it involves the safety of boats and their passengers.
Does anyone else use wave data comparable to my needs?

@mark-ingalls Thank you Mark. I am a new user. Do you think it is ok to make a lengthy and detail post? I have a specific need for the wave/swell data that requires a detailed explanation.
