Why Prince William and Princess Kate always wear blue as fans pick up on trend in new video

Since the release of Kate Middleton’s heart-breaking video which saw her reveal that she has finished her chemotherapy treatment, everyone wants to know one thing.

The video, which was posted earlier this week on their Kensington Royal official X account, shows the family enjoying a day out together, while Kate talks about her treatment and how she’s felt these past few months.

Speaking about her cancer journey over a beautiful slideshow of the Wales' and their children, Kate said: “As the summer comes to an end, I cannot tell you what a relief it is to have finally completed my chemotherapy treatment.

“The last nine months have been incredibly tough for us as a family. Life as you know it can change in an instant, and we’ve had to find a way to navigate the stormy waters and road unknown.”

She added: "Doing what I can to stay cancer-free is now my focus. Although I have finished chemotherapy, my path to healing and full recovery is long and I must continue to take each day as it comes."

She continued: "I am, however, looking forward to being back at work and undertaking a few more public engagements in the coming months when I can.

"Despite all that has gone before, I enter this new phase of recovery with a renewed sense of hope and appreciation of life."

However, all people could focus on after being relieved that the royal is doing well, is that the family was wearing blue. Actually, they noticed that they are always wearing the colour.

After taking in the serious topic, someone pointed out: “On a lighter note, I appreciate this family's commitment to dressing in blue.”

Someone commented below: “Cambridge Blue FOREVER.”

So, why blue?

According to Karen Haller, a Behavioural Colour Psychologist and the author of The Little Book of Color, it’s a significant statement.

She spoke to MyLondon and said: "Wearing the same hue when the Cambridges are showing they are coming together as a family, representing themselves as a cohesive unit.

"When it comes to colour psychology darker blues communicates you are in a position of authority, trustworthy, reliable and can be depended on. You have a sense of duty and take that seriously with committed focus.”

Another author also believes this to be true.

Elizabeth Holmes, author of New York Times bestseller, HRH: So Many Thoughts on Royal Style, it’s on purpose.

She told Vogue: “The royal family is always very aware of the message their clothing sends. A huge part of their very public role is to be seen – as Queen Elizabeth II famously said.

“Before anyone knows what work they are doing, what cause they are supporting, or what event they are attending, we see what they are wearing. They know that and they use that quite savvily.”

She explained: “I think it’s worth considering Catherine’s commitment to blue. For the first official pictures of her as a royal bride-to-be, she wore a vivid blue wrap dress to match the famous sapphire and diamond engagement ring that had belonged to Princess Diana.

"She has since worn every shade of blue, from a soft and pale (one might even call it Cinderella blue) to a deep navy.”
