Because 他の means other in front of a noun.

• 他 = other / another
• の links it to the next noun
• 色 = color

So:

• 他の色 = other colors

This is a very common pattern in Japanese:

• 他の商品 = other products
• 他の人 = other people

In this sentence, 他 is read ほか, so 他の色 is ほかのいろ.

も means also, too, or as well.

So:

• 他の色を見せてください = Please show me other colors.
• 他の色も見せてください = Please show me other colors too / as well.

The も suggests that something has already been shown, and the speaker wants additional options.

For example, maybe the clerk already showed one color, and the customer now says:

• 他の色も見せてください。
  Please show me the other colors too.

Because 見せる and 見る mean different things.

• 見る = to see / to look
• 見せる = to show

So:

• 見てください = Please look.
• 見せてください = Please show me.

In a store, if you want a clerk to show you something, 見せてください is the correct verb.

It comes from the verb 見せる (to show).

The pattern is:

• verb in て-form
  • ください = please do ...

So:

• 見せる → 見せて
• 見せてください = Please show me.

This is one of the most important request patterns in Japanese.

Examples:

• 待ってください = Please wait.
• 教えてください = Please tell me.
• 見せてください = Please show me.

It is omitted.

Japanese often leaves out things that are understood from context. In English, we usually say:

• Please show me other colors too.

But in Japanese, the me does not have to be stated if it is obvious.

So 他の色も見せてください naturally means:

• Please show me other colors too.

The listener understands that the speaker wants the colors shown to them.

Normally, the direct object would often take を:

• 他の色を見せてください = Please show me other colors.

But when も is used, it often replaces を.

So:

• 色を → normal object marking
• 色も → object + also/too

That is why 他の色も見せてください is natural.

This is very common in Japanese:

• 水を飲みます = I drink water.
• 水も飲みます = I also drink water.

The basic order is:

• 他の色も = other colors too
• 見せてください = please show

Japanese usually puts the object before the verb, and the verb comes at the end.

So the sentence structure is:

• [object] + [verb/request]

In English, we say:

• Please show me other colors too.

In Japanese, it is more like:

• Other colors too, please show.

Yes, 他の色 is natural and correct.

Another common option is:

• 別の色 = a different color / another color

There is a slight nuance difference:

• 他の色 = other colors
• 別の色 = a different color

In many shopping situations, both can work, but this sentence with 他の色 sounds very normal.

Examples:

• 別の色を見せてください。 = Please show me a different color.
• 他の色も見せてください。 = Please show me other colors too.

It is polite and standard, but somewhat direct.

It is completely normal in many situations, especially in shops, classrooms, and everyday interactions. But if you want to sound softer or more formal, you could say:

• 他の色も見せていただけますか。
  Could you show me other colors too?

Or add a softener like:

• すみません、他の色も見せてください。
  Excuse me, please show me other colors too.

So 見せてください is polite, but not the softest possible phrasing.

Here, 他 is read ほか.

So the full sentence is read:

• ほか の いろ も みせて ください。

This matters because 他 can have other readings in other words, but in 他の + noun, ほか is the standard reading.

Yes. Japanese often does not mark singular and plural as clearly as English.

• 他の色 can mean another color or other colors
• The exact meaning depends on context

In a store, if several color options exist, it will often be understood as other colors.
If only one alternative is available, it may effectively mean the other color or another color.

So the Japanese expression is flexible, and English translation depends on the situation.
