How the Delphi FMX changes the color of the TButton, with its own icon in the Tspeedbutton

In the FMX framework, TButton and Tspeedbutton differ very little, even after setting the stylelookup to the same appearance style, almost identical.

In mobile development, if you need to implement a return function button, we can add a TButton, set Stylelookup to Backtoolbutton (here the name is Rad Studio 10.1 Berlin version, other versions may be slightly different), This time the button's appearance has turned into a return arrow, and FMX has built in a variety of stylelookup to meet the basic needs of everyday development.

After adding the button and changing the appearance, because the default return button on the arrow icon color is gray, if you need to modify the arrow color, you can set the Icontintcolor property, but unfortunately, the current test can only be set when the style selection of Android, This is related to the icon used in the built-in style, Windows uses Tstyleobject, and Android uses the Ttintedstyleobject
