The website People Wearing Pink: 700+ Years of Images of People Wearing Pink offers a number of paintings showing medieval and Renaissance people depicted wearing pink clothing.
From the website:
I orignally conceived this display to go with the A&S them of Best Use of Pink at War of the Wings III. I received so many compliments on the concept that I decided to put it on the web to share it with more people. Due to space constraints the scope of the original display only featured Western European art. This online version will feature images from as many countries/cultures as possible. It currently contains images from only 700 years of the 1,000 years the SCA time frame covers, 600 CE - 1600 CE.
