Hello, this is Kaori from HIDARI.
Today, I’d like to introduce some color coordination ideas using our original HIDARI Left-handed Planner 2026 and the Polar Bear Book Band.
The Polar Bear Book Band is inspired by the polar bear. According to Inuit legend, all polar bears are left-handed.
This charming common trait makes the polar bear a perfect mascot for our left-handed stationery brand.

Both the planner and the book band come in five different colors, offering plenty of possibilities.
Many customers tell us they have a hard time deciding which combination to choose—and we’re delighted to hear that!
We hope you’ll find a favorite pairing to accompany you in the year ahead.
A Natural Look with Matching Tones
You can’t go wrong with this approach.
Pairing items in the same color family creates a calm and natural impression.

・Peacock Blue Planner × Turquoise Band
A vivid blue-on-blue combination. Bright and refreshing, this pairing is always popular.

・Mango Planner × Beige Band
Warm yellow and beige blend harmoniously. The beige softens the vibrancy of mango.

・Lavender Planner × Gray Band
This gray shade has a subtle hint of purple, making it a perfect match for lavender. Elegant and refined.

・Ivory Planner × Beige Band
Soft tones together create a gentle, understated look.

・Navy Planner × Olive Band
Not exactly the same color family, but both shades are subdued, giving a sophisticated and professional impression.
Add a Pop of Contrast
Next, try mixing different colors.
Using the book band as an accent can make the planner’s color stand out beautifully.

・Peacock Blue Planner × Gray Band
A vivid planner balanced by a lighter band, for a fresh and clean look.
・Mango Planner × Olive Band
Distinctive colors that surprisingly harmonize for a grounded combination.
・Lavender Planner × Turquoise Band
Cool turquoise adds a playful accent to lavender. A staff favorite!
(Turquoise also looks striking with Mango for a bold contrast.)
・Ivory Planner × Red Band
The natural ivory is highlighted by a rich, deep red.
・Navy Planner × Beige Band
A dark base lightened by a pale accent creates a brighter, more approachable feel.
