Hint: In Lobster Data Platform / Orchestration, colors are often stored as 16 bit integers. However, sometimes the color should be used directly in a HTML formatted text or cell content. To achieve this the returned value of this function must only be prepended by a '#' character,
so that it can be interpreted as CSS (cascading style sheet) color value.
Practical example
The color of arbitrary source needs to be rendered in a form. To simulate the color source, it will simply be red from a text field. The following image shows the configuration of the form (as portal).
The 32-bit integer text field with element id '5' simulates the source of the color, which is to be visualized, as integer.
A configured behaviour named 'renderColor' which is triggered on 'Changed' is to write HTML code into the color label (element id '10'), which will therefore render the color.
If the form is now loaded and displayed, the label will render the color which is coded into the text field.
Hint: An appropriate contrast color can be calculated as well, which makes writing into such a label field possible, using the calculation function contrastColor (Calculate contrast color).
