12-Color Comboo Highlighter Fluorescent Markers Set Review: The Ultimate Colour-Coding Kit

Jun 02, 2026

12-Color Comboo Highlighter Fluorescent Markers Set

For students, professionals, and anyone who relies on colour-coding to organise their notes and documents, having the right highlighter set is essential. The 12-Color Comboo Highlighter Fluorescent Markers Set offers an impressive range of vibrant fluorescent colours in a single, comprehensive kit. In this review, we'll explore why this set is becoming a popular choice among UK students and professionals who take their colour-coding seriously.

Why 12 Colours?

Most standard highlighter sets offer 4–7 colours, which is sufficient for basic colour-coding. But for those who need a more sophisticated system — students with multiple subjects, professionals managing complex projects, or anyone who uses colour-coding as a core organisational tool — 12 colours opens up a whole new level of possibility.

With 12 distinct fluorescent colours, you can create a comprehensive colour-coding system that covers every subject, category, or priority level without any overlap or confusion. This is particularly valuable for students preparing for exams, where clear visual organisation can make a significant difference to revision efficiency.

Specifications

Colour Range and Vibrancy

The 12-colour set covers the full fluorescent spectrum, from classic yellow and pink through to less common shades like fluorescent purple, teal, and orange. All 12 colours are genuinely fluorescent, meaning they have that characteristic bright, almost glowing quality that makes highlighted text immediately stand out.

The colours are well-differentiated from each other, making it easy to distinguish between different categories at a glance. This is crucial for an effective colour-coding system — if two colours look too similar, the system breaks down.

Chisel Tip Performance

The chisel tip on the Comboo highlighters offers the same dual-width functionality found on most professional highlighters. The broad face of the tip (typically 4–5mm) is ideal for highlighting full lines of text, while the narrow edge (typically 1–2mm) can be used for underlining specific words or writing annotations in the margins.

The tip is firm enough to maintain its shape with regular use, and the ink flows consistently without flooding or drying out mid-stroke.

Smear Resistance and Bleed-Through

Two of the most common complaints about highlighters are smearing on freshly printed text and bleeding through thin paper. The Comboo set performs well in both respects:

  • Smear resistance: Good on laser-printed and photocopied text. As with most water-based highlighters, some caution is needed with fresh inkjet prints.
  • Bleed-through: Minimal on standard 80gsm paper, and negligible on heavier paper stocks.
  • Dry time: Quick-drying, reducing the risk of smearing when writing over highlighted areas.

Practical Colour-Coding Systems

With 12 colours at your disposal, here are some effective colour-coding systems to consider:

  • Subject-based (students): Assign one colour to each subject — with 12 colours, you can cover up to 12 different subjects without any overlap.
  • Priority-based (professionals): Use different colours to indicate priority levels, action items, deadlines, and reference information.
  • Topic-based (researchers): Assign colours to different themes or topics when reviewing literature or research materials.
  • Calendar and planner coding: Use different colours for different types of appointments, tasks, and events in your planner or diary.

Who Will Benefit Most?

  • University students: Managing multiple modules and subjects, each with their own reading lists and notes, is much easier with a comprehensive colour-coding system.
  • A-level students: Revision is more effective when key information is clearly highlighted and colour-coded by topic.
  • Professionals: Lawyers, accountants, project managers, and other professionals who work with complex documents will find the 12-colour range invaluable.
  • Teachers: Marking and annotating student work is more efficient with a comprehensive colour range.
  • Planners and organisers: Anyone who uses a physical planner or diary will benefit from the visual clarity that 12 colours provides.
