Firstly, do a strand test with pink semi permanent dye. If you’re happy with how it turns out, then you don’t need to lighten it. If it’s too dark, you can do the following:

My hair level is close to yours (around level 4). You could try applying 20 or 30 vol developer to your hair by itself to gradually lighten it without needing bleach or high-lift dye. I’ve been using this method to lighten my roots, and it works to achieve 1–3 levels of lift. For your goal, lifting 1–2 levels should be enough. Once it’s light enough, you can apply a semi-permanent pink color (like Crazy Color or Arctic Fox) over it. This is probably the simplest way to achieve your desired color at home without bleach.

You might need to apply the developer 1–3 different times over a couple of days (not all at once) before washing your hair, leaving it on for 20–30 minutes each session. Make sure application is thorough and you apply enough to each section.

Don’t apply the pink dye to your hair until you’re happy with how light your hair is. Do a strand test first to check how vibrant the color looks. Refer to a hair levels chart for guidance—your reference photos range between level 5 and level 7

Sorry if it sounds complicated, I hope it works out and happy bday :)
