Hi,
1. In next ABMaterial 2.0 because in feedback forum says:
In 2.00 you can create your own colors with an Alpha channel. Note that it has to be set for every INTENSITY you are going to need:
tmpTheme.Page.AddColorDefinition("myred", ABM.INTENSITY_DARKEN4, "#B71C1C", 0.18)
tmpTheme.Page.AddColorDefinition("myred", ABM.INTENSITY_LIGHTEN2, "#B71C1C", 0.18)
Then you can use it as:
tmpTheme.Container("zdepthred").BackColor = "myred"
tmpTheme.Container("zdepthred").BackColorIntensity = ABM.INTENSITY_DARKEN4
While use constants what you will replace, in v ABM 2.0, with your name definition color.
2. You can to build your chooser modalsheet using ABMImage or ABMCard components associateds to ABMButton like a image selector. I think it's easy.
Regards.
