What we are saying is that color should not be relied upon in and of itself, alone, uh, to convey that information. So we're not saying that color cannot be used. Uh, maybe, uh, it-maybe the bars in a bar graph might get text: some other way of conveying that information, in addition, uh, to the colors. In in a Word document, uh, we can get around that by including other text elements, uh, in items. So we want to be very careful about using color alone, uh, to indicate information. For example, if we have a-a figure, uh, and it's preceded by a text description like "items in red indicate a deficit." If the color red alone is used or being used to indicate a deficit, um, then that may significantly impact, um, our color blind users ability to, uh, interpret that information, certainly impact, uh, blind users, uh, ability to, um, interpret that information, uh, as well. We want to make sure the-that we think about color in a way that compliments the information but does not use color alone to convey that information. So color and, uh, color contrast, uh, are going to be particularly important, uh, considerations, uh, for low vision users and color blind users. When we're talking about, um, the contrast ratio, uh, between text, uh, and background, uh, we're talking about the choice of colors that may impact, uh, other users, for example, color blind users. Careful use of color contrast is important to all users.
