+In the problem statement, the colors and their code are already mentioned. So first let us define an array of colors.
+```
+export const COLORS = [
+  'black',
+  'brown',
+  'red',
+  'orange',
+  'yellow',
+  'green',
+  'blue',
+  'violet',
+  'grey',
+  'white',
+]
+```
+
+Now we have an array, we can directly get code by fetching the index of the parameter color in the array and using the Array.indexOf() to achieve our results.
+
+```
+export const colorCode = (color: string) => {
+  return COLORS.indexOf(color); 
+}
+```
