How Do You Read the Japanese Color Name for Grape Purple? Its Characteristics and Name Origin

The Japanese color name 葡萄色 has two established readings: ebiiro and budō-iro. Both can refer to a reddish purple, but the older reading has an etymology that is easy to misunderstand. This article explains the readings, the connection to wild grapes, how historical descriptions vary, and which sample colors to consider when designing a web page.

Why can 葡萄色 be read as both ebiiro and budō-iro?

The traditional reading is ebiiro. Here, ebi originally refers not to a shrimp but to ebikazura, an old Japanese name associated with wild grapevines. The color name evokes the reddish-purple appearance of their ripe fruit. Japanese dictionaries also record budō-iro, a more transparent reading based on the modern word budō for grapes, meaning a reddish purple reminiscent of ripe grapes.

The pronunciation ebi later became associated with the Japanese word for shrimp, leading to overlapping descriptions and spellings such as 海老色. Related names such as ebicha (shrimp brown) should not automatically be treated as one identical color. For the historical name, the relationship with the grapevine is central.

The fruit inspired the name, but that does not mean the traditional dye was made by simply applying grape juice to cloth. Historical dyeing accounts describe using the roots of the purple gromwell plant. Traditional descriptions also range from pale purple to deeper reddish purple; a modern digital color swatch cannot claim to reproduce every historical use of the term.

Compare two HEX samples described as grape purple

HEX is a six-digit hexadecimal notation used to define web colors. One color reference uses ■#6C1C4F for ebiiro. Its RGB values are red 108, green 28, and blue 79. RGB expresses a color through red, green, and blue light components, each ranging from 0 to 255. This sample is a deep reddish purple with a substantial blue component.

Another Japanese color-swatch source calls ■#4F1225 ebiiro. Its RGB components are red 79, green 18, and blue 37, making it darker and relatively redder than the first example. Both are published samples, not competing universal standards for this traditional name. Neither is a precise reproduction of all the shades used historically.

The contrast ratio between the two dark examples is only about 1.33:1. A contrast ratio measures the difference in relative luminance between adjacent colors. Even though their reddish-purple tones differ, they are too close in brightness to serve as the only distinction between different categories or selected and unselected controls.

Using grape purple on an exhibition website

Example 1: Use the color behind a large exhibition heading. For a textile-dyeing exhibition banner, use grape purple ■#6C1C4F as the background with a white ■#FFFFFF heading such as “Japanese Colors: Ebiiro.” That text and background have a contrast ratio of about 10.96:1. Present dates and venue details in an off-white ■#F8F4F0 information panel with dark ink-purple ■#2C2533 text, which gives about 13.52:1. A “View the Exhibition” button can use pale gold ■#E5CFA3 against the grape-purple background, with grape-purple ■#6C1C4F lettering. The button lettering and the button against its surroundings each have about 7.19:1 contrast.

Example 2: Reserve grape purple for headings and buttons. On a page with longer explanations, use off-white ■#F8F4F0 for the large background and grape purple ■#6C1C4F for headings. This pair contrasts at about 10.01:1. Set the body copy in ink-purple ■#2C2533 at about 13.52:1. A “Read About the Color Name” button can use the darker swatch ■#4F1225 with white ■#FFFFFF lettering, giving about 14.53:1. The button’s fill contrasts about 13.27:1 with the surrounding off-white.

In contrast, pale gold ■#E5CFA3 and off-white ■#F8F4F0 have a contrast ratio of only about 1.39:1. Avoid using pale gold for small text or important borders against that light background. Under WCAG 2.2 Level AA, normal text generally needs at least 4.5:1 contrast and qualifying large text at least 3:1. Essential non-text graphics and user interface boundaries may also need 3:1 against their adjacent colors.

HueRoll lets you enter a HEX code, adjust the selected color, and check its contrast against white and black. It does not directly compare arbitrary color pairs or automatically judge AA compliance. Share the exact grape-purple code selected for the project and separately check the actual text, background, and button combinations.
