Hi Venla,
Thank you for your question!
Shade 600 Dark Blonde is the lightest of these three shades. It works well on a light brown to blonde base, and the shade is generally soft, neutral/warm dark blonde with brown undertones.
500 Light Brown is a medium brown shade that is clearly darker than Dark Blonde. The result is a natural brown that doesn’t necessarily have strong reddish or ashy tones.
According to many customer experiences, this shade can sometimes appear darker than expected based on the picture on the package.
515 Iced Chocolate is a brown with a cooler, slightly chocolatey or grayish undertone. It doesn’t lean as much towards warm browns or reddish tones as many traditional brown shades do.
However, please note that the final result is influenced by factors such as the hair's color before dyeing, hair porosity, and condition.
We always recommend testing the shade first on a small hair strand to check the shade's effectiveness on your hair.
I also always recommend consulting your own hairdresser 😊✨
I hope these tips are helpful.
Have a lovely day!
