I have this button

  <button class="btn-submit" type="button" appControlhover [defaultColor]="btnBackgroundColor" [highlightColor]="btnhoverColor" [btnhovertxtcolor]="btnColor"   style="margin-top: 20px"                            
      (click)="Submit()">      Send    </button>

ts code

btnBackgroundColor='#28e979';
btnhoverColor='#a6dabb';
btnhovertxtcolor='#848f90';

Custom Directive:

import { Directive, 
  OnInit, 
  Renderer2, 
  ElementRef, 
  HostListener,
  Input,
  OnChanges,SimpleChanges,
  HostBinding } from '@angular/core';

@Directive({
  selector: '[appControlhover]'
})
export class ControlhoverDirective implements OnChanges {

  @Input() defaultColor : string;
  @Input() highlightColor : string;
  @Input() isValid : boolean = true;
  @HostBinding('style.backgroundColor') backgroundColor: string;
  @HostBinding('style.color') btnhovercolor: string;

  constructor() { }
  ngOnInit(){

    if(this.highlightColor!='none')
    {
      this.backgroundColor = this.defaultColor;
    }
    else if(this.highlightColor=='none')
    {
        this.backgroundColor = this.defaultColor;
    }
    else 
    {
      this.backgroundColor=this.defaultColor;
    }
    
  }
  @HostListener('mouseenter') mouseover(eventData: Event){
    if(this.highlightColor!='none')
    {
      this.backgroundColor =this.highlightColor;
      this.btncolor='#28e979';
    }
    else if(this.highlightColor=='none')
    {
      this.backgroundColor = this.defaultColor;
    }
    else
    {
      this.backgroundColor=this.defaultColor;
    }
  }

  @HostListener('mouseleave') mouseleave(eventData: Event){

    if(this.highlightColor!='none')
      {
       this.backgroundColor = this.defaultColor;
      }
      else if(this.highlightColor=='none')
      {
          this.backgroundColor = this.defaultColor;
      }
      else
      {
        this.backgroundColor=this.defaultColor;
      }
  }
}
