Britain's Duchess Catherine opened an art room at a school in London today (14.02.14).
The 32-year-old royal visited Northolt High School in Ealing this morning to meet with children and staff and officially open the room, which helps struggling pupils through art.
Despite it being Valentine's Day, Catherine opted for a bright blue LK Bennett dress for her appearance.
The school, which is under new leadership after a damning Ofsted report in 2011, was chosen as the location for the seventh art room, which has been open to pupils since September.
Catherine, who has been a patron of the ICAP Art Room charity since 2012, was joined by news presenter John Snow, who is also a patron, and the room will be used by up to 60 students at the primary school, and eventually other children from schools in the borough in west London.
She said: "I am a firm believer in the power of art to make a difference, and The Art Room is providing this on a daily basis."
It was Catherine's second solo engagement of 2014, after she attended the National Portrait Gallery's annual gala in London on Wednesday (12.02.14).
Her appearances mark her gradual return to official royal duties after spending time with her seven-month-old son Prince George, with husband Prince William.
She will attend a number of events in coming weeks before she is joined by William and baby George on a tour of New Zealand and Australia in April.

Britain's Prince William and Prince Harry have been helping to move sandbags in flood-hit Berkshire today (14.02.14).
The royal brothers turned up at 7am at a golf club in Datchet, near to Windsor Castle, where they helped load sandbags onto a crane, according to witnesses. Sources say William, 31, addressed journalists from the Guardian newspaper, who gathered near the site, and asked them: "Why don't you put notepads down and help?"
The reporters agreed to lend a hand but aides intervened and said it would not be possible due to a lack of appropriate clothing.
William and Harry, 29, were filmed carrying the sandbags with 20 members of the Household Cavalry and Network rail staff.
Dressed in waterproofs and Wellington boots, the royals helped move the heavy sandbags onto the back of an army truck.
A Kensington Palace spokesman said of their actions: "They wanted to show their support for the flood victims and have joined the Armed Forces relief effort."
The village has been severely affected by the ongoing floods and water rising in the River Thames and there have been fears the situation could get worse as more rain is expected.
A royal aide also told the Guardian that the pair had been working with members of the Army unit this morning in a number of locations and that it was a "private effort" to help.

Beyoncé has teamed up with Britain's Prince Charles in a bid to raise money for charity at her concerts.
The 'Drunk in Love' singer is encouraging her fans to make £3 donations to The Prince's Trust as part of her global campaign #BeyGood, encouraging people to be kind to their community.
Beyoncé, who is already an ambassador for the charity, said: "As a young child I was blessed to have the support of my family who encouraged me to reach for my goals.
"So many young people don't have this. I am honoured to partner the #BeyGood campaign with The Prince's Trust to help young people beat the odds and create better lives for themselves."
Concert-goers will be given the opportunity to have their seats upgraded to VIP during her 'Mrs Carter Show' dates if they help to raise money for the youth charity.
Chief executive of The Prince's Trust, Martina Milburn, said: "Beyoncé understands that, every day in the UK, young people are facing not only unemployment but also the devastating effects of homelessness, addiction, poverty, bullying and poor mental health.
"All of these hardships can leave them feeling that life isn't worth living. It is up to us to help them get their lives back on track and the funds raised through the #BeyGood campaign will help us to do that."
Prince Charles met the 32-year-old superstar in 2003 at an event in London's Hyde Park and he revealed his son, Prince William, had a crush on her, while his other son, Prince Harry, is also a fan of her music.

A musician is claiming he is the father of Lil' Kim's baby.
Mr. Papers - who was romantically linked to the rapper in 2012 - has taken credit for impregnating the 'Magic Stick' hitmaker after she revealed on Wednesday (12.02.14) she is expecting her first child.
The low-profile hip-hop artist has been bombarded with congratulatory messages on Twitter from his pals, to which he has retweeted to his 4,300 followers.
His friend, Von Killpatrick, wrote: "Congrats to @MR_Papers!!! He gave Kim what she wanted for years. I'm so happy for both of them. (sic)"
Another pal, Donte, added: "Heard All LiL Kim Fans are Looking For My Dawg @Mr_Papers LoL 🙌 Congratz Homie!!! #LiLKim #MrPapers... (sic)"
Mr. Papers then wrote, "I heard everybody looking for me?", before changing his account name to 'Daddy'.
Meanwhile, it has also been reported world champion boxer Floyd Mayweather, 36, is the father of the 39-year-old star's unborn child as they were dating each other up until September last year.
However, the rumours didn't go down well with Mr. Papers, who claims he is "very excited" about becoming a dad and is planning to get married to Lil' Kim.
He told New York Daily News' Confidenti@l page: "I'm very upset people are going around saying this is Floyd Mayweather's child when it's mine. I'm excited to be a dad and am going to marry Lil Kim."
Although Lil' Kim - who is believed to be four-and-a-half months pregnant - is remaining tight-lipped on the father's identity, she is reportedly planning to reveal all in a reality TV show, which will begin filming next month.
