The League One strugglers want a big crowd so have reduced terrace prices to just 25p for juniors and concessions and 99p for adults.
Working with national partners such as Show Racism the Red Card, Kick it Out and the Football League, the two clubs have also agreed that the game should not be segregated, giving all fans the chance to mix and show their support for the cause.
Managing director Steve Thompson said: "Over the years the club has tried to reach out to all members of our community from whatever background and of all ages.
"We are renowned as a family, friendly club and days like these help to reinforce that position."
