Easter colors are a little brighter this year for Mitchell High School junior Mahli Shell.

But her favorite color this week may as well be white, as in the White House.

Shell's artwork was on display Monday in Washington, D.C., as President Trump and the first lady hosted the 141st White House Easter Egg Roll.

Schools all over the nation were invited to decorate or design an egg representing their state's history under specified guidelines. The best-designed eggs were displayed during the Easter Egg Roll, and Shell's was one of those selected.

"She created a beautiful design," said Shell's art teacher, Marica Shannon. "To be chosen was definitely an honor for our department. We were very, very proud of that.

"As far as the students, any time you can see their faces light up and see that sense of pride from something they created, it really has meaning and honor. This was really special."

Shell's egg was inspired by growing up in a Native American culture. It shows a buffalo skull, bear tracks and a portrait of Crazy Horse, among other Native American symbols.

"I'm really excited," Shell said. "I never thought I would be noticed for something like this."

In March, the South Dakota Department of Education approached Mitchell High School - due to its successful art program - to put together a submission for this year's Easter Egg Roll.

Shannon said about 90 high school students participated in the contest, most of them coming from her crafts classes. The rules stated students could design eggs with only gold, red, pink, blue and green, and the design needed to be emblematic of the state.

"This design was her idea," said Shannon, who has been teaching in the Mitchell School District for 25 years. "We, of course, do activities within the classroom to develop their ideas and develop something that they may not have thought at first."

The field was narrowed to the top 10 eggs, and a group of teachers chose Shell as the winner. The egg's design was then turned over to the U.S. Department of Education, which put it on display with the other states' during Monday's White House event. The actual egg Shell designed was not sent to Washington, D.C., but an image of it was displayed.

Shell, 17, said art is a passion of hers "because it helps me express all the experiences I have had in my life."

The White House Easter Egg Roll dates back to 1878 and on Monday brought an estimated 30,000 people to the White House, where one of the main events included children using wooden spoons to roll and race hard-boiled eggs across the lawn. The day also included Easter egg hunts, photo opportunities with the Easter Bunny and decorating stations.
