+## What is going on?
+
+Hello. This is a first step toward color schema flexibility. 
+
+You still can use existing predefined `accent` colors from the list:
+- blue
+- green
+- orange
+- pink
+- red
+
+but if you need to pick another accent colors you can do it with the help of native CSS Variables.
+
+Just create, if you haven't any yet, `static/style.css`
+
+and redefine two CSS variables, like this 
+
+```css
+:root {
+  --accent: blue;
+  --accent-contrast-color: yellow;
+}
+```
+
+### Any other CSS Variable I should know? 
+
+You can find all of them in the browser's page inspector, but here is the list with default values anyway:
+
+```css
+  :root {
+    --accent: #23B0FF; /* 1 of 6 basic colors */
+    --background: color-mix(in srgb, var(--accent) 2%, #1D1E28 98%); /* background color; inherit shades of the accent */
+    --accent-contrast-color: black; /* mainly uses for text on the accent backgrounds but not limited */
+    --color: white; /* text color, also some other text use the variable in color mixing */
+    --border-color: rgba(255, 255, 255, .1); /* border color */
+    --phone: "max-width: 684px"; /* phone breakpoint */
+    --tablet: "max-width: 900px"; /* tablet breakpoint */
+
+    /* code syntax */
+    /* take a look at themes/re-terminal/assets/css/syntax.scss to understand in detail which color stands for */
+    --syntax-func-color: color-mix(in srgb, var(--accent) 70%, #999 30%); 
+    --syntax-var-color: color-mix(in srgb, var(--accent) 90%, transparent);
+    --syntax-value-color: color-mix(in srgb, var(--accent), white);
+  }
+```
+
+
+### Future plans
+Already right now you can play with CSS Variables and achieve decent results, but I hope will work on some light-ish presets and maybe on exposing event more tokens to the users.
