It means that if you have these names internalized (redorange for example, I'm sorry for not using the proper names), then if you see berries in that color then you recognize them easily - those are the only redorange berries I know. Otherwise these are just another red berries to me, I have to notice differences in shape for example. How you divide reality into patterns influences a lot what abstractions you can come up with on top of that. E.g. take evaporation. It's much easier to discover it if you divided things into solids, liquids and gases than if you divided things into fire, earth, water and air. It can get much more subtle like with intro/extroverts or asperger/autism in psychology. It's really hard to compare things and find new patterns between them once you put them into some buckets. You can much more easily find patterns within a bucket. But among different buckets, it's hardly possible, and it seems extremely hard to ignore some pattern once you've learned it.
