+Subpackages, i.e. folders, in this directory have their source of truth in the internal Google
+source code repository.
+
+The code is manually copied because:
+
+- Alternatives are automatically syncing Material Color Utilities from the internal Google source
+  repository, or GitHub.
+- Having Android's core automatically taking updates from code that changes regularly, and can
+  easily affect design, is undesirable.
+
+To update the code:
+
+1. Copy Material Color Utilities (libmonet internally) from the internal Google source repository to
+   this directory.
+2. Replace package definitions. Use Find and Replace in directory, replace
+   com.google.ux.material.libmonet with com.android.systemui.monet.
+3. Remove @CanIgnoreReturnValue and @CheckReturnValue, both usage and imports. Currently only in
+   Scheme.java. Chose removal because only Android /external libraries depend on the library with
+   these annotations.
+4. Copy tests for Material Color Utilities to
+   frameworks/base/packages/SystemUI/tests/src/com/android/systemui/monet/
+5. Remove HctRoundTripTest (~3 minutes to run) and QuantizerCelebiTest (depends on internal source
+   repository code for handling images)
+6. Reformat regular and test code to Android bracing/spacing style.
+   In Android Studio, right click on the package, and choose Reformat Code.
+7. Change tests to subclass SysuiTestCase and use an annotation such as @SmallTest / @MediumTest.

+     * <p>It enforces important properties:<br>
+     * #1. Desired contrast ratio is reached.<br>
+     * As contrast increases from standard to max, the tones involved should always be at least the
+     * standard ratio. For example, if a button is T90, and button text is T0, and the button is T0
+     * at
+     * max contrast, the button text cannot simply linearly interpolate from T0 to T100, or at some
+     * point they'll both be at the same tone.
+     *
+     * <p>#2. Enable light foregrounds on midtones.<br>
+     * The eye prefers light foregrounds on T50 to T60, possibly up to T70, but, contrast ratio 4.5
+     * can't be reached with T100 unless the foreground is T50. Contrast ratio 4.5 is crucial, it
+     * represents 'readable text', i.e. text smaller than ~40 dp / 1/4". So, if a tone is between
+     * T50
+     * and T60, it is proactively changed to T49 to enable light foregrounds.
+     *
+     * <p>#3. Ensure tone delta with another color.<br>
+     * In design systems, there may be colors that don't have a pure background/foreground
+     * relationship, but, do require different tones for visual differentiation.
+     * ToneDeltaConstraint
+     * models this requirement, and DynamicColor enforces it.

+ * A color system built using CAM16 hue and chroma, and L* from L*a*b*.
+ *
+ * <p>Using L* creates a link between the color system, contrast, and thus accessibility. Contrast
+ * ratio depends on relative luminance, or Y in the XYZ color space. L*, or perceptual luminance can
+ * be calculated from Y.
+ *
+ * <p>Unlike Y, L* is linear to human perception, allowing trivial creation of accurate color tones.
+ *
+ * <p>Unlike contrast ratio, measuring contrast in L* is linear, and simple to calculate. A
+ * difference of 40 in HCT tone guarantees a contrast ratio >= 3.0, and a difference of 50
+ * guarantees a contrast ratio >= 4.5.
