White on rice you wouldn’t see a difference…the woman you met was like you that much that you didn’t see a difference.

The most commonly heard use of this expression would be something like this: He was so enthusiastic to learn everything about this subject, he was all over it like white on rice. Well these days of course, not all rice is white any more. But traditionally rice was white only… and the “white” was certainly all over the rice, LOL. It’s a way of trying to say that somebody was into something, or going after something with single-minded purpose, and “all-over” concentration, just the same way that white is all over rice.

Inseparable, in the manner of the color of something from the something.

Usual usage: The fielder was unerringly going to catch the fly ball, he was like white on rice. or

The detective was so inspired by the clues that he was on the killer’s trail like white on rice.

This is not a good description for one person is like another.

The metaphor you gave suggests one active party and one passive party.

You may want: “Like two peas in a pod.” (They are hard to tell apart.)

Like white on rice: it was natural.

To me, the idiom or colloquialism, or let’s just say SLANG (!)…”like white on rice”…refers sometimes to a condition of cloying closeness, or of being close to the point of losing ones own identity, OR–usually–it just means being really ‘on top’ of something one is doing, being right on time with it and up to standards…That’s the most frequent use, that last one.

Example: “I am on it like white on rice.”

But all the above can be used with the phrase “like white on rice” (which is usually not used with the verb is or was …it stands alone)—But I wouldn’t use it to describe a woman who was “like me.”

Did I understand your question correctly?

Some people use the word “doppelganger” to describe people like themselves, but I don’t think that’s right either, since it usually means ghost.

I would just say “She’s like my twin.”

It means, like you are all over it, like white on rice. Like you are on it! It’s happening!

white on rice? means really and totally there on it I think

nope, haven’t met a woman who was like me, they are female

I always joke around and say i’ll be all over you like white on rice…as in i’ll be on your back until somethings done.

Do you mean in color or race then no. There is really no one like me cause I am special and originally designed and made to be only me. Also I am black on rice and what up with that and what is your point?

That means that something was really close together. Maybe refering to friends or someone observing another person. and no I have never met a woman who was like me.
