Build Spotify’s Colorizer Effect with JavaScript

If you’ve used Spotify before, you are likely familiar with the duotone effect. Essentially, this effect works by replacing the whites in a grayscale image with one color, and the blacks with another. Since this redesign was launched in 2015, it has been used on everything from playlist covers to artist images, becoming synonymous with the brand.

There have been multiple takes on recreating this effect using mix-blend-mode in CSS, the CoreImage library for iOS, and even a Canvas implementation. So, what makes this implementation different?

Well, we will be using the globalCompositeOperation feature in HTML Canvas, which will give a duotone effect with only 40 lines of code. Compared to 100+ lines of code in the other HTML Canvas implementation that manipulated every pixel, it is more efficient while making the code more readable.


Why use the Canvas API?

In my case, I planned to generate personalized images with the favorite music for each user. I wanted to export the canvas as an image, so the user can save the image to their device.

You might be able to implement this with CSS and use a library like HTML2Canvas to export it as an image. However, this involves external libraries and the documentation for that particular library states that it does not support filter or mix-blend-mode properties, which are the building blocks of the CSS duotone implementation.

The Canvas API is a means for drawing graphics via JavaScript and the HTML [<canvas>](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/canvas) element. Our purpose fits nicely within the built-in capabilities of Canvas.

A simple process of developing music streaming app like Spotify

Spotify is a music streaming app that allows users to listen to music without downloading. Daniel Ek founded it in 2006. In 2015, its net worth was more than $5 billion. The Spotify company has received $½ billion as a fund from 17 investors. But, currently the additional amount of $500 million has been added to the fund.

Spotify is not the first one to enter the online music service industry. But, it was an innovator by implementing marketing approaches, technology, and subscriptions. Due to these, it has become the preferable music streaming app among users across 170 countries.

In 2013, it had 6 million subscribers with 24 million active users. And, it has grown to 15 million subscribers with 45 million free users in 2015.

Since the user base started to rise in 2011, they announced that music streaming services would be limited to 10 hours for a month after listening to unlimited music of 6 months. Later in 2014, this limitation was removed.

In 2020, Spotify hit 155 million subscribers and its net worth is $9.5 billion.

In 2021, the revenue from the Spotify app is expected to reach $10.83 billion.

This clearly shows that the number of subscribers has increased and the app’s revenue is also increasing.
