This tool is a virtual gallery where you can view 8 representative masterpieces in your browser, including Ukiyo-e, which hold an important place in art history from the Renaissance to Post-Impressionism.

The database comes with a fixed collection: "Mona Lisa", "The Starry Night", "Water Lilies and Japanese Bridge", "Girl with a Pearl Earring", "The Scream", "The Kiss", "The Birth of Venus", and "The Great Wave off Kanagawa".

Instead of calling an external museum API or Wikimedia search each time, it loads pre-configured artwork data and fixed images hosted directly on the same site.

In the center of the screen, the selected work is displayed with a frame, and a caption indicating the artist and creation year is placed below it.

The right information panel displays the art style, location, and a concise description of the artistic background. Switching to fullscreen mode hides the search panel and color information, allowing you to focus on the painting itself using the entire exhibition area (this operates as a maximized layout within the browser viewport, not an OS-level fullscreen; click the "Exhibition room full screen" button in the header to switch, and use the minimize icon to return to the original layout).

A search and categorization function is provided to quickly locate a specific painting among the 8 included works in the gallery collection.

Typing a keyword into the search panel on the left side of the interface will check for matches within English titles and English artist names.

Because the dataset strictly uses English strings, Japanese keyword searches are not supported; however, typing terms such as "Gogh" or "Mona Lisa" will immediately filter and list the corresponding matching artworks.

Additionally, the art style dropdown menu allows you to filter works by specific styles linked in the database, such as "High Renaissance" or "Impressionism".

You can also filter by hue type, selecting from three broad color tendencies: "warm", "cool", and "neutral". All these search and filtering processes are executed locally within the browser.

Whenever a search or filter combination yields zero matches, the exhibition list becomes empty, the selected painting and its details are cleared from display, and slideshow playback stops with isPlaying set to false.

In this situation, an empty-state message prompts you to change your filters or search query, and pressing the Previous or Next navigation controls will do nothing.

When results are restored by adjusting your criteria, the gallery automatically selects the first matching painting.

The tool features a slideshow function that automatically cycles through the paintings in the exhibition list at fixed intervals.

Clicking the Play icon on the exhibition control panel starts the slideshow, automatically advancing to the next work every 5 seconds based on the sequence of the current list order.

If you have filtered the works using the search or style filter, the slideshow will loop only within that filtered list. For example, selecting "Impressionism" will limit playback specifically to paintings in that category, as there is no option to select multiple styles simultaneously.

To pause, click the Pause icon to halt automatic switching at the current work, or manually switch paintings using the chevron arrows on the sides of the exhibition area.

When filtering or searching results in zero matches, the selected painting and its details are cleared, playback stops with the internal isPlaying status set to false, and an empty-state message asks you to change your filters or search keywords.

Attempting to click Previous or Next while the list is empty will do nothing, and restoring valid results automatically selects the first match.

To simulate the atmosphere of a physical gallery, the tool provides wall texture and lighting adjustments. You can choose from four wallpaper styles: a profound "Dark", a classic "Wood", a modern "Concrete", and a bright, neutral "White".

These are rendered using CSS background colors and gradients, instantly changing the background of the exhibition space with a single click.

Additionally, three lighting modes are available. "Spot" applies a circular shadow overlay that draws attention to the center, recreating a dramatic display.

"Dim" intentionally lowers the overall brightness to simulate a dark room environment. "Window light" creates a soft atmosphere by overlaying diagonal light streaks, as if natural light is entering the room.

Combining these visual effects lets you experience how the same painting looks under different conditions, but please note there is no export function to save the exhibition wall and lighting display as an image.

The right information column displays a "color palette" linked to each masterpiece. These are not generated by real-time image analysis or exact color extraction; rather, they are 5 carefully selected hexadecimal color codes (e.g., #121b44) fixed for each work.

For instance, "The Starry Night" has 5 distinctive colors ranging from deep blue to yellow, while "The Kiss" features 5 colors centered around gold and brown.

A Copy icon is placed next to each color block, allowing you to save the HEX code to your device's clipboard. The gallery confirms color swatch copying only after system clipboard write fulfillment, displays a manual selection field if automatic copying fails, and immediately invalidates active copy feedback upon painting selection, filtering, or gallery navigation.

This feature provides direct access to the color balances of masterpieces for design inspiration.

This tool displays 8 fixed JPEG images hosted within the site. The original primary source and individual licensing conditions for each local JPEG are not fully recorded or verifiable on this screen.

You must separately consider the copyright of the original physical artwork and the terms of use for the digital reproduction. While the right panel lists the owning institution (e.g., the Louvre or MoMA), this only indicates the physical location of the original piece and does not unconditionally guarantee that the digital reproductions used here are cleared for commercial use.

If you intend to reuse the images, incorporate them into secondary creations, or use them in commercial designs, you must independently verify the official terms of the respective institutions and the original image distributors.

While operations like changing walls or searching are processed locally in the browser, loading the images and subsequent access involve standard HTTP communication.

Please enjoy this tool for color reference and viewing purposes, without relying on its display as an absolute guarantee for reuse.
