The colour theme is centred around soft pastel tones, chosen for not only visually soothing but also create a sense of harmony and calm, helping to build a peaceful and trustworthy environment, especially important when children are learning foundational elements like the alphabet. 

The illustration style follows the same thoughtful approach, using clean, simple graphics that are easy to understand, by avoiding overly complicated details, the design helps young learners stay focused and engaged, making the learning experience both enjoyable and effective.
