Feel in Colour

A mindful journaling app where colour becomes a language for emotion.
A mindful journaling app where colour becomes a language for emotion.
A safe space to pause and check in with yourself.

Haven is a gentle journaling app designed to support emotional reflection without pressure. Instead of relying on words alone, it uses colour as an emotionally intuitive cue to help users check in with themselves when language feels difficult.

Discovery

Journaling felt overwhelming, not supportive

Through research and reflection, a consistent pattern emerged:

  • People wanted to journal, but the tools available often made the experience feel intimidating, clinical or effort-heavy.

  • Journaling often felt like something they should do, rather than something that emotionally supported them.

The core issue wasn’t motivation—it was emotional friction created by design choices.

Define

Designing for emotional safety, not productivity

Most journaling apps prioritise output: streaks, analytics, progress indicators. While effective for habit tracking, these features often conflict with emotional vulnerability.

Problem

Journaling tools unintentionally pressure users by framing reflection as a task rather than a personal, emotional experience.

Ideate

Translating emotion into colour

Haven’s emotional language is inspired by aura rings and aura photography, using colour as an intuitive way to express internal states. This approach is supported by colour psychology research, which suggests emotional responses to colour often occur before cognitive interpretation.

Colour is not decorative; it functions as emotional feedback.


Prototype

Designing an interface that responds with care

For colour to feel meaningful, the interface needed to acknowledge emotion without disrupting reflection.

As users move through guided prompts, the interface subtly adapts to their emotional check-in. These changes are intentionally gentle, creating a sense of being acknowledged without judgement or evaluation.

Testing & Iteration

Refining emotional responsiveness through user feedback

What we tested:

  • Live colour changes during writing

  • Fixed prompts vs user-controlled prompts

  • Neutral prompts vs mood-responsive prompts

What we learned:

  • Live colour feedback disrupted focus

  • Fixed prompts felt emotionally misaligned

  • Generic questions broke the emotional flow

Key changes:

1) Removed live colour changes during writing

Dynamic colour shifts caused distraction

Outcome

A calmer, more intuitive way to reflect

These changes shifted Haven from a reactive interface into a supportive guide:

  • Users stayed focused longer during journaling

  • Reflection felt conversational rather than evaluative

  • Colour became a moment of meaning after reflection, not a distraction during it

Reflection

What designing Haven taught me

Designing Haven reinforced that emotional UX is often about removal, not addition.

  • Reducing stimulation improves focus
    Removing live colour changes helped users stay present while writing.

  • Control increases emotional comfort
    Allowing users to guide their own prompts reduced pressure.

  • Language shapes emotional safety
    Small changes in tone and timing significantly affected how supportive the experience felt.
