Did you know that you can customize Windy colors for almost any layer? What is the point of doing it? You may prefer your own color palette, but also, by this way, you can deal with some specific requirement.
For example, it may be helpful to visualize a particular level of temperature from which you consider that it may hurt people and your environment. By using a particular color you will be alerted just by looking at the map.
If you are fan of boating, you may use a color like red - the usual sign of danger - when the wind reaches a certain force. And as everyone does not have the same threshold of danger for outdoor activities, it is better to set the threshold by yourself. In the example below the red color was used from 28 knots of wind, i.e. 7 Beaufort which is an usual warning level for a coastal cruiser boat.
Details are shown here.
But there are other reasons, such as the case of a Windy user who is green blind. It was better for him to replace this color with another one.
How to change a layer color scale?
This change can only be made via the website windy.com, not in the phone app, and you need to be logged in. But when the change has been made on desktop, it will automatically be applied also on the phone or tablet application.
Go to Settings and choose Customize Color Scale. Select the layer you want to edit.
You may want to customize the Waves layer. If you are fond of paddling on the seashore or if you are a transoceanic sailor, you will not consider the same scale for waves height.
Selecting the Waves layer you get this table:
In the first column, you can change the steps of the scale and/or, in the second column, the colors.
You know that colors on your screen is a mix of 3 base colors: Red, Green, Blue, which are specified by the RGB code with 3 numbers as you see in the second column like rgb (192,51,95)
How to modify the RGB code
When you click a color line you open a small window which allow you to change the hue (1) and the density/brightness (2).
You can use some RGB palette like this one:
The first tool, RGB color picker, is similar to the Windy tool here above. The second one, RGB color codes charts, is easier to use. Click a color, note the 3 figures for RGB and type them in the Windy table.
When you are satisfied with your colors, click Save. At any time you can switch back to the Windy default settings by clicking Load defaults
And for example you can get this type of colors scale for waves:
If you want to obtain directly this color scale just look at this thread in Windy community:
