The purpose of this code – an example for chromatic scales, gradients and heat maps in MQL4.
To simplify the work uses the RGB color model and the standard conversion function StringToColor .
You can implement other ways to convert, but we decided to use the RGB color model to simplify the mathematical operations with flowers.
