This letter is one of a set of alphabets designed to give different effects. In this case shades of pink have been used to contrast with the dark blue background. Using the darkest as the outline and fading to a very pale pink in the centre encourages the illusion that the letter is three dimensional and embossed. All these letters can be worked to different sizes and proportions so that you can have short fat letters or tall skinny letters - this one is a square.
