Aragones claimed that it was not intended to be racist but the remark sparked outrage in England.
Arsenal manager Arsene Wenger called on him to say sorry to Henry in person.
Sources within the Football Association said that there had been no direct apology. But the England squad will today wear anti-racism T-shirts during this afternoon's training session.
Told about the bibs that the English team were wearing this afternoon, Aragones said: "I don't know if the English football team were wearing these bibs to make a point. I say again - to be a racist is a question of conscience and mine is clear. Thierry Henry and myself have common friends and he knows it was just a way of motivating a player.
"I am a citizen of the world and I've a lot of coloured people who are friends. I don't know why people go on and on about it. I'm not a racist."
His midfielder Guti today highlighted the importance of Real Madrid team-mate David Beckham to England.
Guti has been widely regarded as the player who suffered most from Beckham's arrival at Madrid in 2003 and is often considered his closest rival for a place in the starting line-up.
However, on his return to the Spain squad, Guti was full of praise for the England captain.
"Beckham is decisive wherever he plays, he is dangerous with set pieces and his passing is important given the players they have in attack," he said.
Guti also claimed he was fully focused on the friendly, despite the biggest club game in Spain - Real Madrid against Barcelona - taking place this Saturday.
"All I am thinking about now is Spain v England," he said.
"What we have to talk about here is how to stop (Wayne) Rooney, Beckham or (Frank) Lampard."
