Define host text, editing, clipboard, and accessibility service contracts.

```yh
external CreateNativeUiDisplayColorCapabilityV1(text displayId, bool available, bool profileAvailable, text profileIdentity, bool advancedColorSupported, bool advancedColorActive, bool hdrSupported, bool hdrUserEnabled, bool wideColorSupported, bool wideColorUserEnabled, bool policyLimited, text activeMode, text encoding, int bitsPerChannel, int sdrWhiteMilliNits, text discovery, text source) returns nativeUiDisplayColorCapabilityV1
```


## Use CreateNativeUiDisplayColorCapabilityV1

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.
text displayId = "display Id"
bool available = true
bool profileAvailable = true
text profileIdentity = "profile Identity"
bool advancedColorSupported = true
bool advancedColorActive = true
bool hdrSupported = true
bool hdrUserEnabled = true
bool wideColorSupported = true
bool wideColorUserEnabled = true
bool policyLimited = true
text activeMode = "active Mode"
text encoding = "encoding"
int bitsPerChannel = 1
int sdrWhiteMilliNits = 1
text discovery = "discovery"
text source = "example"
nativeUiDisplayColorCapabilityV1 result = CreateNativeUiDisplayColorCapabilityV1(displayId, available, profileAvailable, profileIdentity, advancedColorSupported, advancedColorActive, hdrSupported, hdrUserEnabled, wideColorSupported, wideColorUserEnabled, policyLimited, activeMode, encoding, bitsPerChannel, sdrWhiteMilliNits, discovery, source)
Console.Log("Inspect result in your debugger")

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.host_ui_services__createnativeuidisplaycolorcapabilityv1"
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--CreateNativeUiDisplayColorCapabilityV1/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


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