Color Variations
All versions of RexLex use the same basic color scheme, which has been selected to give the maximum distinction for all shapes.
There are currently 5 variations of the font, which differ slightly in the amount of contrast that they have against the white background. Pure black provides the best contrast vs a white background, but the least distinction between letters. So these two conflicting attributes have to be balanced against each other. The various RexLex levels give users the option to pick the right balance for them. Also each screen implements color a little differently so users have to judge which is best based on their screen and personal preference. Most people have been selecting levels 2 or 3, but it’s entirely up to each person. You may even decide that brighter colors of level 1 are better in the beginning while memorizing the colors, but later switch to the darker ones of levels 3 or 4.
Level 1 has more bright primary colors but less contrast vs white.
Level 2 is shifted more towards darker colors, like navy blue, forest green and burgundy.
Level 3 is darker
Level 4 is the darkest and easiest to see against white, but the letters are not quite as distinct from each other.
Mixed - This version keeps the primary colors from level 1 if they are dark enough, but darkens the lighter colors like light blue. It keeps most of the variation in hue but less variation in brightness.
