'Red' is the colour; 'read' (past tense) is pronounced exactly like 'red' — it is the past of 'to read'.
Adjective/noun. The colour at the long-wavelength end of the visible spectrum. The colour of blood and stop lights.
The warning light turned red as soon as we started the engine.
She wore a red dress to the awards ceremony.
The accounts were in the red by the end of the quarter.
Verb. Simple past and past participle of 'to read'. Pronounced /rɛd/ — identical to 'red'. The infinitive 'read' is pronounced /riːd/.
I read the entire report on the flight home last night.
Have you read the new policy document yet?
She had read every book in the series before the film came out.
Common mistake
In speaking, 'I read it yesterday' and 'I red it' sound identical — which causes writing errors. People sometimes spell the past tense as 'red': "I red the email" (correct: I read the email). Or spell the colour as 'read': "Her dress was read" (correct: red).
Trick to remember it
'Red' the colour is short and simple — three letters, easy to picture. 'Read' the past tense has an EA in the middle — the same EA as in 'lead' (led) and 'spread' (past is also spread). The EA vowel changes sound between present /iː/ and past /ɛ/.
Quick rule
Is it the colour? 'Red'. Is it the past of to read? 'Read' (pronounced /rɛd/).
Did you know?
'Read' is one of English's rare heteronyms — same spelling, different pronunciation. Present tense: /riːd/. Past tense: /rɛd/. This irregularity comes from the Great Vowel Shift (1400–1700), a massive change in English vowel pronunciation. During this period, vowels shifted systematically, but past tenses often preserved older pronunciations. The result: the same word spelled identically but sounding completely different depending on tense.
