A computer-implemented method for providing color transformations, comprising: providing a user interface layer comprising a user interface manager and a transform manager, wherein the transform manager is a computer service providing color transformation functions to the user interface manager; receiving, at the user interface manager, a request from a client for accessing an application; responsive to the request, retrieving, by the user interface manager, a file from the application, wherein the file is utilizable for rendering a user interface by a browser to access the application; intercepting, by the user interface manager, the file prior to being sent to the browser for rendering the user interface; analyzing, by the transformation manager, content elements of the file defining a user interface screen in order to obtain a color of each content element; upon obtaining the color data of the content elements and responsive to a user selection of a source color and a replacement color: for each content element of the user interface screen, comparing the color of the content element to the selected source color, if the color of the content element falls within a predetermined threshold distance of the selected source color along a color palette, converting the color of the content element to a representative target replacement color based on the replacement color, wherein converting the color of the content element to the representative target replacement color includes performing a color transformation based on a color space HSL, wherein H is the hue, S is the saturation and L is the lightness, said color transformation including determining a distance vector separating the color of the content element from the selected source color along the color palette and converting the saturation and lightness of the color of the content element to the representative target replacement color based on the replacement color and the distance vector, and following processing of the content elements, displaying the user interface screen on a display device, including the converted color element(s). providing a user interface layer comprising a user interface manager and a transform manager, wherein the transform manager is a computer service providing color transformation functions to the user interface manager;
