jeśli spojrzeć na colors.js plików z biblioteki materiałów kątowe, można odkryć, że nie jest to opcja, która pozwala nam skonfigurowany stan efekt kursorem:
/**
* @ngdoc directive
* @name mdColors
* @module material.components.colors
*
* @restrict A
*
* @description
* `mdColors` directive will apply the theme-based color expression as RGBA CSS style values.
*
* The format will be similar to our color defining in the scss files:
*
* ## `[?theme]-[palette]-[?hue]-[?opacity]`
* - [theme] - default value is the default theme
* - [palette] - can be either palette name or primary/accent/warn/background
* - [hue] - default is 500 (hue-x can be used with primary/accent/warn/background)
* - [opacity] - default is 1
*
* > `?` indicates optional parameter
*
* @usage
* <hljs lang="html">
* <div md-colors="{background: 'myTheme-accent-900-0.43'}">
* <div md-colors="{color: 'red-A100', 'border-color': 'primary-600'}">
* <span>Color demo</span>
* </div>
* </div>
* </hljs>
*
* `mdColors` directive will automatically watch for changes in the expression if it recognizes an interpolation
* expression or a function. For performance options, you can use `::` prefix to the `md-colors` expression
* to indicate a one-time data binding.
* <hljs lang="html">
* <md-card md-colors="::{background: '{{theme}}-primary-700'}">
* </md-card>
* </hljs>
