During their visit to Tobermory on the Isle of Mull, Catherine's newly lightened locks were prominently visible as the couple began their two-day tour of the Inner Hebrides, situated off Scotland's western mainland coast.
At age 43, Catherine's transformation from her signature dark brown hair to a warmer caramel shade marks a significant change. Her hair has been gradually becoming lighter in recent appearances.

The couple's wedding anniversary coincided with their Scottish visit, with reports from news.com.au indicating they planned a private celebration at a local self-catering accommodation.
For the Scottish engagement, Catherine wore a Holland Cooper blazer paired with brown skinny jeans, a blue linen shirt and brown boots, according to The Mirror.
Her accessories included a Cartier timepiece, believed to be a third anniversary present from William, alongside two necklaces, one featuring initials of her children.

The royal couple exchanged vows at Westminster Abbey on April 29, 2011, in a grand ceremony watched by viewers worldwide, marking the marriage of the late Princess Diana's eldest son and heir to the throne.
This overnight visit to the Inner Hebrides represents Catherine's - known in Scotland as the Duchess of Rothesay - first extended tour since revealing her cancer diagnosis last year.
