例えば、『ねえ、ちょうど今青い四角の紙を見たよ。』のようにだ。

、『、。』。

For example, like 'Hey, I just saw a blue square piece of paper.'

Literal

For-example, 'hey, just now blue square paper [object-を] saw [informative-よ]' [like-のように] [copula-だ].

『』 are alternate Japanese quotation marks, used inside 「」 or in stylized text. ~のようにだ ('like [example], that is') is a set phrase closing a comparison with the copula — literary/written feel. The embedded direct speech uses casual forms (ちょうど今, 見たよ).
