Colorblind Friendly Heatmap For Website

Guess what? I recently got a request from a user who wanted a colorblind-friendly heatmap for Howuku. Since I didn't know much about colorblindness, I decided to do a quick Google search and stumbled upon a fascinating article about Coloring for Colorblindness. That's when I thought of asking GPT-4 for help.


If you don't know what GPT-4 is or you've been living under a rock, let me give you a quick rundown. GPT-4, short for Generative Pre-trained Transformer 4, is a cutting-edge AI language model developed by OpenAI. It's the hottest tech and everyone have been talking about it where it is capable of understanding and generating human-like text based on the context provided.

What makes GPT-4 so remarkable is its ability to perform a wide range of tasks, from answering questions and summarizing articles to creating entire blog posts or even writing code. In our case, GPT-4 played a vital role in helping us digested an article about colorblindness and implement a colorblind-friendly heatmap function for Howuku.

Viridis Color Scheme

To my surprise, GPT-4 suggested a fantastic color scheme in no time! Even though I still don't know much about colorblindness, here is what I did.

But, with just the Hex code is not good enough as the scroll depth can be anywhere in between those color 0.235, 0.667 etc. Let's just say something that is more flexible and make it write more code for me.

There we go! We got a working colorblind-friendly heatmap within just 10 minutes. How crazy is that??

FYI, GPT-4 chose the Viridis color scheme, which uses colors that smoothly transition from dark blue to bright yellow, making it easier for colorblind users to differentiate. It even went ahead and transformed that color scheme into a JavaScript function for me.

I've got to say, AI is incredible these days! It's like having a super-capable and very underpaid intern who can do everything you asks it! 😈

Now, Howuku has this new heatmap that's way more accessible for colorblind folks. We did some testing, and it looks like it works perfectly. I even tried out some online tools that simulate different types of colorblindness to make sure it's really good for everyone.

It is really amazing to see how GPT-4 made this happen so quickly. I didn't have to spend hours learning about colorblindness or messing with code – it just did everything for me. I'm genuinely impressed with what AI can do for web development and analytics, and it's got me thinking about all the other ways we could use it to improve Howuku.

Honestly, this whole experience has been thrilling. I can't wait to see what other incredible things AI like GPT-4 can help us do in the future!

Colorblind Mode in Howuku Heatmap

Oh, and before I forget, let me tell you how to activate the colorblind mode in Howuku heatmap. It's super easy!

When you're viewing a heatmap in Howuku, just look for the "Colorblind Friendly" option.

Click on it, and voilà! You're all set. The heatmap will now use the colorblind-friendly Viridis color scheme.

Benefits of the Viridis Heatmap Mode for All Users

Not only is the Viridis heatmap mode great for colorblind users, but it also offers better visual clarity for everyone. That's because the colors in the Viridis palette are perceptually uniform, meaning the differences between colors are consistent across the entire range. This makes it easier to spot patterns and trends in the heatmap, helping you make better-informed decisions based on the data.

So, give the colorblind mode in Howuku heatmap a try, and let me know what you think! I'm confident that with the Viridis heatmap mode, our colorblind users will have a much better experience when analyzing their data. And who knows, you might find it useful too, even if you're not colorblind! It is just so BEAUTIFUL!
