'The belief that all members of each race possess characteristics, abilities, or qualities specific to that race, especially so as to distinguish it as inferior or superior to another race or races.'

That is the definition of racism. There's no mention of a specific colours. Anyone can be racist. No matter what colour they are. To suggest otherwise is naive and ridiculous. Some cases of racism may be worse than others, but that doesn't mean that it shouldn't be taken as seriously.
