Are Mikan Color and Orange the Same? Comparing Color Codes and Swatches

Mikan-iro, the Japanese name for the color of a mandarin orange, and orange are both vivid orange-family colors, but they do not always refer to the same numerical value. In web design, it is especially important to distinguish the Japanese color name from the CSS color keyword orange. Let’s compare three published color swatches and consider how to use them on a product page and an announcement banner.

Mikan color and orange are similar, but their HEX codes differ

Mikan-iro (蜜柑色) takes its name from the peel of the satsuma mandarin. The Japanese color reference Wairo Daijiten lists ■#F08300 as one example, while I-IRO lists ■#E98900. CSS (the language used to style text, backgrounds, and other parts of web pages), on the other hand, assigns a fixed value of ■#FFA500 to the color keyword orange. In everyday speech, “orange” can refer to a broad range of shades; the CSS keyword names one specific color.

HEX is a hexadecimal color code written with a hash sign and six digits or letters. RGB describes a screen color using red, green, and blue light components. These three swatches show the actual values reported by the respective references.

The two Mikan swatches, ■#F08300 and ■#E98900, have a contrast ratio of about 1.01:1, meaning their relative brightness is very similar. CSS orange ■#FFA500 has a higher green RGB component and appears somewhat more yellow than either Mikan sample. Sample A ■#F08300 and CSS orange ■#FFA500 have a contrast ratio of around 1.34:1. A contrast ratio measures the difference in relative luminance between colors; it does not indicate whether their names are equivalent or whether a combination looks good.

Compare a mandarin product card and an autumn promotion banner

Example A: a direct-from-grower mandarin product card.Use warm off-white ■#FFF8EF behind the fruit photos and dark brown ■#302920 for the product name, growing area, and price. Give a small “In Season” label a Wairo Daijiten Mikan-orange ■#F08300 fill with dark brown ■#302920 lettering. Use deep green ■#235047 for the “View Product” button, with white ■#FFFFFF text. Dark brown on off-white provides approximately 13.61:1 contrast, dark brown on the Mikan label about 5.43:1, and white on the deep-green button about 9.09:1. The label stays small so that the actual fruit photographs remain the main visual focus.

Example B: an autumn fruit-fair announcement banner.Make the main background deep blue-green ■#243B3D and place a short “Fruit Fair” heading and the date in off-white ■#FFF8EF. Fill the “Explore the Fair” button with CSS orange ■#FFA500 and use dark brown ■#302920 for its label. The heading contrasts with the background by approximately 11.27:1, the button text with its orange fill by about 7.27:1, and the orange button fill with the surrounding blue-green by about 6.01:1. If you prefer the I-IRO Mikan shade ■#E98900, try it as an alternative for a button or small accent instead of placing several nearly identical oranges side by side.

Watch out for white text and distinctions based only on orange shades

White ■#FFFFFF lettering on the Wairo Daijiten Mikan orange ■#F08300 has only about 2.64:1 contrast, while white ■#FFFFFF on CSS orange ■#FFA500 has only about 1.97:1. Neither reaches the WCAG (Web Content Accessibility Guidelines) 2.2 Level AA requirement of at least 4.5:1 for normal-sized text or 3:1 for large text. Choose dark text on these bright orange fills instead.

Do not distinguish states such as “Registration Open” and “Closed” using only two similar orange shades. Include the status in words, and use shapes or sufficiently contrasting borders where the distinction is important for operating the interface. HueRoll lets you adjust colors with HEX input and check a selected color’s contrast against white or black. It cannot compare arbitrary pairs of colors or automatically determine WCAG conformance, so verify the actual text, button, and background combinations separately in the finished design.
