B11. Value, Contrast and Legibility

Five connected studies move value, contrast and legibility from direct observation and explanation through controlled experiment, application and critique. Five active studies connect evidence, experiment, application and critique.

Observe → Understand → Experiment → Apply → Critique and record

• Value Structure

  Begin Value, Contrast and Legibility with value structure: observe directly and record the conditions before interpreting the result.

• Luminance

  Within Value, Contrast and Legibility, build a working explanation of luminance, keeping the model distinct from the appearance it describes.

• Text Contrast

  In Value, Contrast and Legibility, test text contrast by changing one controlled variable and comparing the evidence.

• Non-Text Contrast

  Apply non-text contrast within Value, Contrast and Legibility to a practical color decision, preserving both the reasoning and its constraints.

• Grayscale and Low-Vision Checks

  In Value, Contrast and Legibility, critique grayscale and low-vision checks against evidence, exceptions and failure conditions before carrying it forward.
