Learn Hardcore Swedish: Om allt går bra kommer hon att känna sig tryggare i starka färger nästa vecka. - If everything goes well she will feel more confident in strong colors next week.

In Swedish, the idiomatic way to say “if everything goes well” is Om allt går bra, literally “if everything goes well”, using the verb gå (to go) plus bra (well).

Using är bra would sound more like “if everything is good”, which is about a state, not about how things turn out. When you’re talking about success or outcome of a plan, Swedes normally use:

Det gick bra. – It went well.
Hoppas att allt går bra. – Hope everything goes well.

So Om allt går bra is the natural choice here because it’s about how the situation turns out, not about whether everything is good right now.

What does Om mean here, and how is it different from När?

Om here means “if” and introduces a condition: Om allt går bra = “If everything goes well”.

Om = if (condition, it may or may not happen)
- Om det regnar, stannar vi hemma. – If it rains, we’ll stay home.
När = when (something is expected/definite in time)
- När det regnar, blir det blött. – When it rains, it gets wet.

In this sentence we don’t know yet whether things will go well, so Swedish uses Om, not När.

Why is the word order Om allt går bra kommer hon … and not … hon kommer …?

Swedish main clauses normally follow the V2 rule: the finite verb (here kommer) has to be in the second position in the main clause.

The sentence has two parts:

Subordinate clause: Om allt går bra – If everything goes well
Main clause: kommer hon att känna sig tryggare … – she will feel more confident …

When you start the sentence with a subordinate clause, that whole clause counts as position 1. Then, by the V2 rule, the finite verb of the main clause must come next:

Om allt går bra (position 1), kommer (position 2) hon (position 3) …

If you start directly with the main clause, you can also say:

Hon kommer att känna sig tryggare i starka färger nästa vecka om allt går bra.

Here hon (she) is in position 1, kommer stays in position 2. Both versions are correct; the first just foregrounds the condition (If everything goes well…).

What is the function of att in kommer hon att känna? Is it necessary?

Att is the infinitive marker, like “to” in English “to feel”.

känna = (to) feel
att känna = to feel

In standard, slightly formal or neutral written Swedish, the pattern kommer att + infinitive is common for future meaning:

Hon kommer att känna sig tryggare. – She will feel more confident.

In everyday spoken Swedish, many people drop att after kommer:

Hon kommer känna sig tryggare.

Both are grammatically fine; kommer att känna sounds a bit more careful or formal, kommer känna more colloquial.

Why do we say känna sig and not just känna?

Känna sig is a reflexive verb meaning “to feel (a certain way, emotionally or physically)” about yourself or your state.

känna by itself is more general: to feel, sense, know, be acquainted with
- Jag känner henne. – I know her.
- Jag känner smärta. – I feel pain.
känna sig = to feel (in oneself, in a certain state)
- Jag känner mig trött. – I feel tired.
- Hon känner sig tryggare. – She feels more secure/confident.

Because the sentence describes how she herself feels (her degree of comfort/confidence), Swedish needs the reflexive sig.

Why is it tryggare and not mer trygg?

Tryggare is the regular comparative form of the adjective trygg (safe, secure, comfortable/confident). For most one-syllable adjectives, Swedish forms the comparative by adding -are:

stor – större (big – bigger)
snabb – snabbare (fast – faster)
trygg – tryggare (safe/secure – safer/more secure)

Mer trygg is not wrong, but it sounds less natural here. Native speakers strongly prefer tryggare in this kind of sentence.

So:

Hon känner sig trygg. – She feels secure.
Hon känner sig tryggare. – She feels more secure.

What nuance does trygg / tryggare have compared to English “confident” or “comfortable”?

Trygg is a key Swedish word that covers ideas of:

feeling safe, secure
feeling at ease, not anxious
often also emotionally safe/secure

In this context, känna sig tryggare i starka färger suggests:

she will feel safer and more at ease, less self-conscious;
she will feel more comfortable and confident wearing strong colors.

Depending on context, trygg can translate as:

safe: Ett tryggt hem – a safe/secure home
secure/stable: ett tryggt jobb – a secure job
comfortable/confident (emotionally): Jag känner mig trygg här. – I feel safe/comfortable here.

So tryggare here is very close to “more comfortable and confident (in herself)”.

Why is it i starka färger and not med starka färger or i de starka färgerna?

Preposition: “in” vs “with”

Swedish uses i in expressions like “to feel comfortable in (clothes/colors)”:

känna sig trygg i starka färger – feel comfortable in strong colors
känna sig bekväm i jeans – feel comfortable in jeans

Using med would sound more like “with strong colors” as an accompaniment, not as something you’re wearing or surrounded by.

Indefinite: “starka färger” vs definite “de starka färgerna”

starka färger (no de, no -na) = strong colors in general, as a style.
de starka färgerna = the strong colors (specific ones already known from context).

Here the meaning is that she’ll feel more confident in strong colors in general, as a type of clothing style, so the indefinite starka färger is appropriate.

Where can nästa vecka go in the sentence? Can the word order change?

Yes, nästa vecka (next week) can be moved, as long as you respect the V2 rule in the main clause. Some natural options:

Original:
- Om allt går bra kommer hon att känna sig tryggare i starka färger nästa vecka.
Time adverbial earlier in main clause:
- Om allt går bra kommer hon nästa vecka att känna sig tryggare i starka färger. (A bit more formal/literary, but correct.)
At the very beginning (then inversion again):
- Nästa vecka, om allt går bra, kommer hon att känna sig tryggare i starka färger.

All of these are grammatical. The differences are mainly in emphasis and style. The original is the most neutral and typical in everyday language.

Could we say Om allt går bra, ska hon känna sig tryggare i starka färger nästa vecka instead of kommer hon att känna? What’s the difference between ska and kommer att?

You can use ska, but it changes the nuance:

ska often implies:
- intention, plan, decision, obligation
  Hon ska börja träna. – She is going to / should start working out.
kommer att is more neutral and predictive:
- what you expect to happen, less about intention
  Det kommer att regna. – It’s going to rain.

In your sentence:

… kommer hon att känna sig tryggare …
= more like a prediction: she will (probably) feel more confident…
… ska hon känna sig tryggare …
can sound like this is a goal, plan, or expectation, even a bit like “she is supposed to feel more confident”.

For a neutral, “future-as-result” meaning, kommer att känna sig is usually the best choice here.
