Hi there,

Thanks for reaching out. I tried to replicate on my end, and it looks fine for me.

So, would you be able to share the file link with access to support-share@figma.com? It won’t affect your billing. I hope I can investigate it further.

Also, I changed the category to “Ask the community” because the “Share an idea” is used for feature request.

Thanks for your understanding!

Hey @y_toku,

I’m having a similar issue and wanted to check if you’re sure you are replicating the gradient correctly:

The original gradient has opacity 0 on the end colour:

background: linear-gradient(90deg, #f00 0%, rgba(255, 168, 0, 0) 100%);

Whilst you have set it to 1 hence the different results:

background: linear-gradient(90deg, rgba(255, 0, 0, 1), rgba(255, 168, 0, 1));

I’m also getting this code from a Figma gradient:

background: radial-gradient(50% 50% at 50% 50%, #E0BAFF 0%, rgba(0, 255, 209, 0.00) 100%);

Which on the browser will not show any of the end colour as its opacity is 0, whilst in the file the gradient looks like this:

Sorry if I’m, wrong just thought I’d reply as someone experiencing a similar problem!

Hi there,

It seems we need more investigation with our support team, could you reach out directly to the support team with a copy of your file: https://help.figma.com/hc/en-us/requests/new? Our support team will look into it/

Please make sure you use the email associated with your Figma account, include links to the file in question, and share access with support-share@figma.com. Don’t worry, inviting us to view your file won’t impact your billing.

Thanks!

Hiya, I’m experiencing issues with gradient behaviour with opacity too. Although different to this issue, I wanted to add to the thread.

I’m discovering that gradients don’t fade as expected.

When set to 0%, I’d expect the gradient to fade to nothing.

Instead, they create a ‘stripe effect’ at the tail end of the gradient.

When two gradients are overlaid, this ‘stripe’ is even more evident.

Please could you advise whether this is a bug or not? And any suggestions to solve this in the meantime.

I’m working on an iOS App Store app icon and facing the same issue when exporting a PNG file with a gradient-filled background. The App Store always tells me the image has an alpha channel, which is weird. I don’t want to use JPEG format, but I have no way to fix this issue.

Hi there,

Could you submit a bug report detailing the steps that led to this issue? You can do so by following the link: https://help.figma.com/hc/en-us/articles/360041468234-Submit-a-bug-report. Our support team will investigate it further.

Thanks,

They’re optical illusions. The white stripe isn’t really there; you can check it with the eyedropper tool, or observing that the bottom part is already pure white, so there can’t be a “more white” stripe there. As you can imagine, the “cross” illusion is just two of those effects, overlaid on top of another.

The illusion is caused by a sudden stop of the linear gradient, causing our eyes/brain to amplify the edge’s contrast. This can be reduced by changing to an easing gradient.

There are a few resources how to achieve this:

• Easing Gradients (the images above are from this website)


• Easing Linear Gradients | CSS-Tricks

It appears that there are some Figma plugins for this, too:

• https://www.figma.com/community/plugin/907899097995668330/easing-gradients


• https://www.figma.com/community/plugin/781591244449826498/easing-gradient

With those plugins, you can compose overlaid gradients without the “cross” illusion in the corner:

Let’s label the gradient:

     Color A  +---------+  Color B

100% opacity  +---------+  0% opacity

We’re interested in what’s happening in the middle, so 50% of the way through the gradient.

Figma shows 50% of color B, at 50% opacity.

The browser shows 0% of color B, at 50% opacity.

I would lean into the direction of Figma rendering it correctly. It shows all the intermediate colors, so the orange color “leaks” into the gradient from the right side. Makes sense to me.

On the other hand, browsers use the alpha-premultiplied color space. As a result, it doesn’t matter what color you set on the other end - all hues will render exactly the same. To me, this is a weird behavior, because the browser ignores the color of the end stop.

I assume this creates problems when handing off the designs to developers. If they use the CSS as-is, they might not have the same result as shown on designs.

Possible solutions:

• Manually add the middle gradient stop, and set it to orange at 50% opacity.


• If you don’t want Figma’s effect, use the same colors on A and B ends of the gradient, and only set different opacities.


• Tell your developers to use a solid gradient, with a mask that’s another gradient. (See below)


• Convince Figma to automatically calculate the intermediate gradient stops, so Figma’s rendering can be replicated in browsers that render it “wrong”. Tagging @y_toku.


• Convince W3C to allow disabling alpha-premultiplied behaviors, which currently completely ignore the color stops.

Figma’s rendering:

CSS (will cause this issue):

background: linear-gradient(to right, red, rgba(0, 0, 255, 0));

CSS (fixed):

background: linear-gradient(to right, red, blue);

mask-image: linear-gradient(to right, white, transparent);
