+# Updates (OpenHarmony 3.1 Beta -> OpenHarmony 3.1 Release)
+
+### Added Validity Verification for Color Values in Color.json
+
+Validity verification is added for color values in the **color.json** file. The verification rules are as follows:
+
+- The hexadecimal color code is used in any of the following formats:
+    - #rgb: red(0-f) green(0-f) blue(0-f)
+    - #argb: transparency(0-f) red(0-f) green(0-f) blue(0-f)
+    - #rrggbb: red(00-ff) green(00-ff) blue(00-ff)
+    - #aarrggbb: transparency(00-ff) red(00-ff) green(00-ff) blue(00-ff)
+- The dollar sign ($) is used to reference resources defined in the application. The format is as follows:
+    - $color:xxx
+
+**Change Impacts**
+
+If the verification rules are not met, an error is reported during compilation.
+
+**Key API/Component Changes**
+
+None
+
+### Restrictions on Declaring Multiple Data Types of State Variables
+
+If a **@State**, **@Provide**, **@Link**, or **@Consume** decorated state variable supports multiple data types, they must be all simple data types or references at one time.
+
+Example:
+
+```ts
+@Entry
+@Component
+struct Index {
+  // Incorrect: @State message: string | Resource = 'Hello World'
+  @State message: string = 'Hello World'
+
+  build() {
+    Row() {
+      Column() {
+        Text(`${ this.message }`)
+          .fontSize(50)
+          .fontWeight(FontWeight.Bold)
+      }
+      .width('100%')
+    }
+    .height('100%')
+  }
+}
+```
+
+**Change Impacts**
+
+When the defined state variable type contains both the simple data types and references, an error is reported during compilation.
+
+**Key API/Component Changes**
+
+If the defined state variable type contains both the simple data types and references, change the type to one of them, as shown in the preceding sample code.
