## Use nativeUiDisplayColorCapabilityV1

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using host.ui_services

// Define host text, editing, clipboard, and accessibility service contracts.
nativeUiDisplayColorCapabilityV1 sample = nativeUiDisplayColorCapabilityV1("display Id", true, true, "profile Identity", true, true, true, true, true, true, true, "active Mode", "encoding", 1, 1, "discovery", "example")
Console.Log(Text.From(sample.schema))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.host_ui_services__nativeuidisplaycolorcapabilityv1"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

[[dependencies]]
package = "host.ui_services"
version = "0.1.0"
path = "../../../yeho/packages/host/ui_services"

```

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

```sh
./yeho/build/dolphin-metal/yehoc ./api-examples/host.ui_services--nativeUiDisplayColorCapabilityV1/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## nativeUiDisplayColorCapabilityV1.Validate

A complete caller for this public method. Sample inputs are illustrative; native resources require their owning lifecycle.

Verification: type checked

```yh
using host.ui_services

// Validate.
nativeUiDisplayColorCapabilityV1 instance = nativeUiDisplayColorCapabilityV1("display Id", true, true, "profile Identity", true, true, true, true, true, true, true, "active Mode", "encoding", 1, 1, "discovery", "example")
text result = instance.Validate()
Console.Log(Text.From(result))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"

Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
