Random Quote Machine Review needed

Here is my project: https://codepen.io/rohangayen/full/RRBxEQ/
Can you please help me by gining me a review for this?

And I want to add some animation effect before loading new quote, how can I achieve this?

Great job, looks good and works well. In terms of the interface, some of the random colors that are displayed aren’t the most aesthetically pleasing and aren’t very easy on the eyes.

As far as the HTML code, it’s a good idea to get into the habit of adding the HTML, HEAD, and BODY tags, as you’ll eventually need to add those anyway once you start developing without CodePen. Also, you should wrap all of your JavaScript inside the $(document).ready function.

Is it possible to filter out all light colours by seeing the RGB value? I have been able to filter out white colour only.
