Listen to this deep dive on Exploring What Colours Can Rabbits See

Read Transcript
Picture this. You've just brought home this vibrant, you know, bright red toy for your bunny. You wave it enthusiastically

and you get absolutely nothing,

right? Just a total blank stare. So, today on a deep dive down the rabbit hole, we are looking at exactly why that happens

because it's a very common experience.

It really is. Our mission for this deep dive is to explore how your rabbit actually sees the world. We've pulled from a bunch of veterinary athmology papers and behavioral studies, and it turns out Our world isn't black and white, but uh it definitely isn't a rainbow either.

No, it's not. That blank stere you get, it basically comes down to biology. As humans, we have tri chromatic vision,

meaning we use three types of cone cells.

Exactly. We use them to pick up red, green, and blue light. But rabbits, however, have diromatic vision. They only have the cones for blues and greens.

Oh, interesting. So, it's less like an old black and white movie and more like, I don't know, applying a really aggressive cool tone filter on a photo app.

That is a much more accurate way to look at it. Yeah. All the reds and oranges just sort of desaturate into these gray shadows while the blues and greens pop.

Wow.

Yeah. So, to a bunny, a bright red strawberry sitting on green grass just looks like a gray blob on a green background.

Which totally explains why they sometimes fumble around trying to find a treat right under their nose until they finally smell it.

Exactly. And you know, because their eyes were on the sides of their heads, they have this nearly 360 degree panoramic view.

Wait, but if they have a 360°ree view, there has to be a blind spot, right? Are they basically blind right in front of their noses?

They are. Yeah. They trade that central resolution and depth perception for the ability to just constantly scan for predators from almost any angle.

It makes sense for a prey animal.

It does. And because they are kpuscular,

meaning they're most active at dawn and dusk,

right? Because of that, their retinas are just packed with rod cells. These act like um biological night vision goggles.

Oh, wow. Yeah, making them highly sensitive to motion and shadow in dim light. But they sacrifice colorful details in the process,

which completely changes how we should interpret their behavior, honestly. Like, if they're looking through this dim blue green filter, what about the whole myth that the color red is actually scary to them.

Oh, yeah.

I mean, I've seen rabbits thump and run away from red objects.

Well, since they can't really process the color red, the color itself just isn't the trigger. If a red object unsettles them, they are reacting to, you know, its unfamiliar shape, its scent, or maybe a sudden movement you made while holding it.

That is so fascinating. So, knowing they rely heavily on those cool colors in motion, that changes everything about how we set up their habitats.

It really does. We should be swapping out all those red and yellow items for blue and green toys.

Maybe throwing in a green fleece or a blue tunnel so the items actually stand out to them visually.

Definitely. And contrast plays a huge role here, too. So, placing light colored objects on darker surfaces makes it much easier for them to identify shapes.

What about lighting? Because you mentioned the night vision rods earlier,

right? So, those rods mean you should never leave artificial lights on for them at night. They need a totally dark, quiet space to rest with just natural lighting and some shaded areas during the day.

I get that. But, I mean, I'm looking at my bunny's pen right now. It's mostly beige.

Yeah.

Brown willow branches, cardboard.

Usual setup. Yeah.

Right. If their vision is already that muted and are navigating mostly by smell and whiskers anyway. Does throwing a blue toy in there actually make a difference?

It really does. While scent and texture are undeniably crucial.

Okay.

Yeah. It adds a distinct layer of visual enrichment which just makes their space genuinely more stimulating.

So if they really are ignoring the reds and seeking out the blue toys, we shouldn't just take the researcher's word for it, right? I feel like can test this biological quirk right in our living rooms.

You absolutely can. You can set up a simple observation. Just line up identical blocks or balls, you know, one red, one green, one blue,

okay?

And over a few days, swap their positions and just watch which one your rabbit investigates the most.

You just have to ensure the shape and scent remain identical. So, you're only testing the visual cue.

Exactly. Though, obviously, individual differences matter, too.

Like with albino rabbits, right? I know they lack pigment in their eyes, which makes them incred sensitive to bright light,

right? So, their visual experience is going to be different. They require much dimmer environments for sure.

But regardless of breed or sensitivity, vision always plays a role in how they interact

because they're constantly reading body language and posture.

Exactly. So, providing a well-lit space with visible blue and green tunnels helps them feel secure, which translates to, you know, more confident interactions with you.

That makes total sense. Your rabbit's vision is just perfectly evolved for their survival. And by simply switching to blue and green accessories, you can build a more enriching environment for your companion.

Just working with their natural instincts.

Exactly. Well, before we wrap up this deep dive, consider this. The next time you walk into your rabbit's room, think about how your own silhouette and the colors of the clothes you're wearing might look to a creature constantly scanning a 360° blue and green world.

That is a really great point.

Yeah. So, maybe skip the bright red sweater if you want their attention. It might just save you from getting that utterly blank stare.
