Spalding High School pupils said #HelloYellow and raised hundreds of pounds for World Mental Health Day.
Pupils at the school were invited to wear something yellow or bring a yellow item in while donating 50p on October 10 raising £406 for the Young Minds charity.
A spokesman for the school, said: “We were wearing yellow to show young people they are not alone with their mental health.
“It is important for us all to know that keeping mentally healthy is just as important as being physically healthy.
“At a time when it is needed most, we hoped that the students would unite to support #HelloYellow and show solidarity to young people.
“Our aims were to raise lots of money for a fantastic cause but also raise awareness of mental health issues amongst young people, in addition to signposting them to further support if they need it.
“We hoped that this day would also show students that they are not alone and that there is nothing wrong with asking for help.
“As always, our students and staff rose to the challenge and it was wonderful to see so many wearing yellow as they came through the school gates.
“There was a lovely atmosphere around school with many forms taking part in the Young Minds #Helloyellow quiz during morning registration.
“Other activities included sessions on: raising awareness of what mental health is in addition to the Young Minds charity and what they do, a kindness challenge, practising mindfulness techniques and how to be aware of your own self esteem.”
The spokesman continued on the work of Young Minds: “There is a wealth of information available on their website on different mental health conditions, but also life events that may negatively affect a young person such as coronavirus anxiety or exam stress.”
