What is an important practice to perform before posting an image with text on a colored background?

Ensuring strong contrast between text and background is crucial when posting an image with text on a colored background because it directly impacts readability and accessibility. High contrast ensures that the text stands out against the background, making it easier for viewers to read and absorb the information being presented. This is particularly important in social media marketing, where quick consumption of information is common. If the text blends too closely with the background color, it can lead to confusion and disengagement from the audience, negating the effectiveness of the message being communicated. Strong contrast not only increases the visual appeal of the content but also enhances user experience, allowing the message to be conveyed clearly.
