• 66/ – Double intensity of the primary tone (which is a deep red in this case).

• /46 – The first number (4) represents a red tone, and the second number (6) represents a violet tone.

This means Koleston 66/46 is an intense red-violet shade.

If you're asking about how this color looks in sunlight, it will likely appear vibrant and reflective, with rich red tones that become more intense under direct light, and violet undertones that may become visible depending on your base hair color and the lighting conditions.

🌟 Koleston 66/46 (Intense Red Violet) – How It Looks & How to Maintain It 🌟

🔆 How It Looks in Sunlight

• In direct sunlight, the red tones will appear more intense and fiery, making the hair look super vibrant.

• The violet undertones may become more noticeable under different lighting conditions, especially in the shade or indoors.

• On lighter hair (blonde/light brown): The red-violet will show up vividly, especially in the sun.

• On darker hair (brown/black): The red tones may be more subtle, but will still reflect light beautifully.

💆‍♀️ How to Maintain the Color

🔥 Use Sulfate-Free Shampoo – Helps prevent color from fading too quickly.
🚿 Wash with Cool Water – Hot water strips color faster.
☀️ UV Protection – Sun exposure can fade reds fast, so use a UV-protectant spray or wear a hat.
🩷 Color-Depositing Conditioner – Red and violet pigments fade quickly, so use a red or violet color mask weekly.
