Enhanced Colour Scheme Assessment Tool (COSAT 2.0) embodies the colour rules and colour selection guideline with an aim to improve the usability of the web page on colour selection by considering the colour combination, colour contrast, and colour luminance. The software development lifecycle used in developing the system is the agile methodology for this study. It takes a webpage and uses the rules of colour as limitations in determining colours selection based on the colour scheme guideline. The result reveals that the webpage testing feature and colour palate testing feature rates at an average of 4.13/5 (about 83%) and 4/5 (80%) respectively. This result indicates that the features function well, and the users find the features useful in terms of functionality. Furthermore, the overall rating is given by respondents (from UAT evaluation) averages at 3.67 out of 5 which is more than 70% satisfied with the performance of COSAT 2.0. when using this tool, its overall performance, and its functionalities.
