As Design Systems grow, so does their complexity. More themes, components, states and accessibility requirements mean more combinations to design, implement, test and maintain.

Consider a Design System with 2 modes, 6 surface contexts, 3 semantic groups, 2 densities, 4 button variants and 6 interaction states. For buttons alone, that’s 2 × 6 × 3 × 2 × 4 × 6 = 1,728 possible combinations.

Maintaining the system is a headache; auditing its accessibility, a project in itself. And throwing AI at the problem doesn’t help, because speed can’t fix a masterfully built house of cards.

Reducing decision complexity

IPAX tackles this design problem with proven software engineering principles: abstraction, encapsulation, and composition rules that bring combinatorial complexity back under control.

The combinations stay. But the decisions needed to manage them now fit on a single screen.

With an implementation effort comparable to adding dark mode, IPAX turns your existing Design System into an Adaptive Design System: one architecture capable of supporting as many modes as you need.

Governing contrast accessibility from a single screen

IPAX consolidates the color relationships that determine contrast compliance into an auditable view. When those relationships meet the required criteria, the resulting color combinations inherit that compliance across the Design System.

This architecture works as a supporting layer for your existing Design System, preserving the components, design decisions and workflows your team already relies on.

LIght mode, 6 x 2 contexts, derived from a single orange brand color definition.
Reader mode (lower contrast, warm ink-paper relationship) with IPAX Score audit layer.
Dark mode with blue accent tones and glassmorphism. IPAX Score takes opacity into account, making sure the full Ink, Paper and Accents matrix will meet WCAG requirements.
Text-on-background samples with WCAG, APCA and IPAX scores, alongside a floating panel explaining ergonomic criteria.
Font size comparator overlaying two typefaces (one in cyan, one in red, with the overlap in white) to compare minimum readable size.
IPAX Design Lab view with colors ordered by luminance, each swatch annotated with its WCAG, APCA and IPAX scores, plus floating panels showing CMYK values and a full contrast matrix.

The IPAX System derives Design System variants from a manageable set of concrete decisions, with an accessible color and typography architecture designed around WCAG 2, APCA and optical ergonomics.

IPAX for Enterprise

Custom solutions, enterprise tools, specialized consulting and hands-on training.

From addressing specific accessibility or maintenance problems to refactoring existing components, developing dedicated tools or establishing a single source of truth for your Design System.

How we work

Your existing components and workflows are the starting point.

We examine your existing Design System, its accessibility vulnerabilities, emerging risks and architectural constraints, alongside your design and development roadmap.

We apply IPAX to your visual identity and representative components, so you can see how the architecture can address your specific challenges. From that foundation, we define the scope, deliverables and implementation plan together.

Who we are

Kambrica is a UX consultancy founded by Santiago Bustelo, an interaction designer since 1996. He founded IxDA Buenos Aires in 2009 and served as the first IxDA Regional Coordinator for Latin America.

Over his career, he has given more than 100 talks and workshops in 24 cities, taught at 11 universities across Argentina, the US, Chile and Colombia, and served as a jury member for the Interaction Awards and MIT Innovators Under 35. Through Kambrica, he has led over 1,000 projects across more than 40 industries.

We’ve been working on the complexity of interface systems since before the term Design System existed. Back in 2011, we presented at Microsoft CodeCamp an approach to modular interface development and testing based on components, combinatorics and pairwise testing.

Today we develop and apply IPAX, presented at Rosenfeld Media, bringing software engineering principles and ergonomics research into Adaptive Design Systems, where accessibility and scalability are addressed at the architectural level rather than treated as separate implementation problems.
