He intentado diferentes formas de obtener el valor de selección y no puedo hacer que funcione
 <body> <select> <option value="black">Black</option> <option value="blue">Blue</option> <option value="green">Red</option> </select> <br> <svg id="svg" style="width:75%; height:500px; border:1px solid black"></svg> </body> <br> <script> document.addEventListener('DOMContentLoaded', () => { document.querySelector('select').onchange = () => { colors = this.value; console.log(colors); console.log(this.dataset.value); console.log(this.data-value); }; }); </script>

También intenté usar this.data['value'] y prácticamente agoté todas las posibilidades.

Errores: incluye draw.html:35 no definido Error de tipo no detectado: no se pueden leer las propiedades de undefined (leyendo 'valor') en HTMLSelectElement.document.querySelector.onchange (draw.html:35:38)
