On the 73rd anniversary of the D-Day invasion, black and white photos newly rendered in color bring history to life.

Brazilian artist Marina Amaral used Photoshop to color both iconic and unfamiliar images of the largest amphibious invasion in history for the June 6 anniversary.

"I love coloring photos that I know will have an impact on people," Amaral told the Washington Examiner. "D-Day is a very important date and I always wanted to do a series to celebrate the anniversary."

The colorized photos show American, British and Canadian soldiers in boats preparing to land on the beaches of Normandy, marching through the countryside, medics helping soldiers reach land, and casualties along the beaches.

Amaral detailed on her website the process behind coloring each image.

"Every completed work has gone through long and in depth research, and is supported by the opinions of experts in each particular area if necessary, to faithfully reproduce the original colors and atmosphere," her website says.

Amaral said coloring the photos took her three days and nights, and added that she has seen positive responses from people.

"I wish I had time to work on more pictures, but I'm glad people liked these ones that I did," she said.

More than 160,000 Allied troops landed on French coastline at five landing spots known as Omaha, Utah, Gold, Juno and Sword in the early hours of June 6, 1944 to stop Nazi advancement. More than 5,000 ships and 13,000 aircraft supported the troops, but a strong German resistance led to more than 9,000 Allied casualties. Despite the high number of Allied casualties, the invasion marked a turning point in World War II and paved the way for the defeat of Nazi Germany.
