Would it be feasible to incorporate a custom (HEX) color into a material component in Angular 4? For instance, like so:
<div *ngFor="let factor of factors">
<button md-button color="factor.color">Button</button>
</div>
In this scenario, factor.color is represented as a string in HEX format (e.g. '#CCC')
You can easily change the color of an element using the [style.color] attribute, and there are helpful resources available for converting hexadecimal code to RGB values:
HTML:
<button mat-button [style.color]="hexToRgb(factor.color)">Click me</button>
Typescript:
....
hexToRgb(hex) {
hex = hex.replace("#",'');
let arrBuff = new ArrayBuffer(4);
let vw = new DataView(arrBuff);
vw.setUint32(0,parseInt(hex, 16),false);
let arrByte = new Uint8Array(arrBuff);
return 'rgb(' + arrByte[1] + "," + arrByte[2] + "," + arrByte[3] +')';
}
