Examined sphere's even colour (6)

Ross

I believe the answer is:

peered

I'm a little stuck... Click here to teach me more about this clue!

'examined' is the definition.
The definition and answer can be both to do with perception as well as being past participle verbs.
Maybe there's an association between them I don't understand?

'sphere's even colour' is the wordplay.
'even' means one should take alternating letters (letters in even-numbered positions are used).
'colour' becomes 'red' (red is a kind of colour).
The alternating letters of 'spheres' are 'pee'.
'pee'+'red'='PEERED'

Can you help me to learn more?

(Other definitions for peered that I've seen before include "Having been made a Lord < examined" , "Look searchingly" , "Looked through narrowed eyes" , "Looked closely" , "Looked searchingly" .)
