Yellow Heart Emoji Meaning: Friendship, Snapchat Best Friends and the So-Called Secret Code

Of all the coloured hearts, the yellow one is the easiest to send without overthinking it. It's sunny, it's kind and it doesn't carry the weight of a red heart. That's also why people worry about it. If a crush sends 💛 instead of ❤️, is that a polite step back? If a colleague uses it, is it too much? Below, I'll go through where it came from, what it says in each kind of chat, the Snapchat label and the scare story that went round in 2025.

Why yellow reads as friendship, not romance

Dictionary.com puts it plainly: the yellow heart can convey love like any heart, but its colour often gets used to show liking and friendship, as opposed to romantic love. Its entry links that to what yellow symbolises, which is happiness, positivity and hope. Think sunshine.

So the yellow heart sits in a useful middle spot. It's warmer than a thumbs up and lighter than a red heart. Dictionary.com notes that it's handy among friends, family and other relationships where a red heart may seem a bit much. That's why you'll see it under birthday posts for a sister, in a group chat after someone shares good news and in thank-you messages to a teacher.

It also shows up whenever something's yellow. Emojipedia says coloured hearts are often used to show an affinity with people, places, groups or ideas linked to the same colour, so a yellow heart can just mean 'I love this yellow dress' or 'come on, team' if your side plays in yellow.

Where 💛 came from: Unicode 6.0 and a hairy pink glitch

Emojipedia lists Yellow Heart as approved in Unicode 6.0 in 2010 and added to Emoji 1.0 in 2015. Dictionary.com adds that it arrived alongside the rest of the original rainbow of heart emojis, and that across platforms it shines with a golden hue.

It hasn't always looked that way. Emojipedia records that on Android 4.4 this emoji showed up as a pink 'hairy' heart, and suggests the oddity came from someone misreading the black and white reference images Unicode supplies. If an older relative ever sent you a strange fuzzy pink heart and meant yellow, that's why.

The Snapchat yellow heart: your number one best friend

Snapchat gives the yellow heart a second, technical job. Dictionary.com says that in 2015 the app started using 💛 to mark two users who are each other's '#1 Best Friends', the person you send the most snaps to and get the most snaps from. Emojipedia adds that the yellow best friend heart turns into a red heart after two weeks of keeping that top spot.

So if you spot a yellow heart beside a name in Snapchat, nobody typed it. The app put it there because of how often the two of you snap. If you want to know how the rest of the ranking works, I've explained the Snapchat best friends list and its emoji labels in a separate guide.

That 'secret code' from the Adolescence drama

In 2025, the British TV drama Adolescence had a scene where a teenager explains coloured heart 'codes' to his father. Emojipedia's write-up of the show says the yellow heart was described there as 'I'm interested. Are you interested?', and plenty of news coverage repeated the list as if it were a fixed rule.

Emojipedia's own verdict is more measured. It says the idea that every coloured heart carries one hidden meaning has more in common with digital chain mail than with linguistic truth, and that hearts broadly convey affection, appreciation or emotional connection, with colour adding tone rather than a secret message. Some groups may use a colour in a special way for a while, but that doesn't make it universal.

If you're a parent and a yellow heart in your child's messages worries you, Emojipedia's advice is the simplest one: ask them, calmly, what it means to them. Most of the time it's just a friendly heart.

Yellow heart from a crush, a mate, your mum or a colleague

Here's how I'd read it depending on who sent it. It's a guide, not a rulebook, because the rest of the conversation always matters more than the colour.

Who sent 💛	What it usually means	A good reply
A close friend	Love you, glad you're here	Send one back, or a 🥰
Someone you're dating	Warm and happy, often softer than ❤️	Match their tone; don't read it as a rejection
A crush you've just met	Friendly interest, keeping it light	Keep chatting and let the words lead
A parent or grandparent	Proud of you, thinking of you	A heart back or a quick 'love you too'
A colleague	Thanks, nice work, good vibes	A 'thank you' or a 🙌 is plenty
Under a sports or fashion post	Love this yellow thing	No reply needed

If you're stuck on a crush's yellow heart, look at the words around it and how often they start the conversation. That tells you far more than one emoji's colour.

Sunflowers, team colours and other yellow pairings

Emojipedia studied which emojis turn up next to each heart. It found that the yellow heart most often appears with other coloured hearts, especially blue, green, purple and red, which suggests people string hearts together as a rainbow more than they pick one with care. It also found 🌻 Sunflower is a popular partner, a bit of colour to brighten up a message.

• 💛🌻 Sunshine and happiness, often for a birthday or a good-news post
• 💛✨ Sparkly, cheerful praise
• 💛🥺 A soft, slightly emotional thank you
• 💛💙💚💜 A rainbow of love, no single colour meant

Made-up yellow heart messages and replies

These are made-up messages to show how it's used, not real chats:

• 'Thanks for coming to the hospital with me today 💛' Gratitude between friends, no romance implied.
• 'Happy birthday to my favourite person 💛🌻' A warm, bright birthday wish.
• 'Had the best time tonight 💛' From a date, it's happy and sincere, just less intense than a red heart.
• 'Great job on the launch, everyone 💛' A team lead being kind without getting soppy.
• 'Matchday tomorrow 💛💛' Support for a team that plays in yellow.

If someone calls you their pookie and adds a yellow heart, it's affectionate and playful, nothing more mysterious than that.

My take on using 💛 on a business account

If you run a business account, the yellow heart is one of the safest hearts you can use. It feels friendly without feeling flirty, so it works when you're thanking a customer for a review, replying to a kind comment or welcoming new followers. I'd pick it over a red heart for anyone you don't know well.

Where I'd hold back is in a formal complaint thread or anything sensitive. A heart, even a yellow one, can look flippant when someone's upset. In those moments, use words. And don't build a campaign around a 'secret meaning' of the yellow heart, because as Emojipedia points out, those meanings shift and aren't shared by everyone.
