Quick summary

• The colorname system colours a monster's name tooltip so you can read the level gap between it and your character before you engage.
• Seven colors carry the reading, from grey through purple.
• Grey is the one that reads oddly. The English publisher page gives 0 percent experience for grey and says it depends on your character level, while the Korean official page says the experience varies with character level and points to a table.
• Purple is the other disagreement. The English page marks the purple trophy as possible with 200 percent experience. The Korean official page marks it as impossible.
• Both pages publish the experience-by-level-difference tables as images, so the numbers below are the color table, not the level tables.

How the colors read

With the Color Name System, the player can see the level difference between the monster and the player in color. The English publisher page describes the colors this way.

• Grey: "No need to face each other." Trophy: impossible. Experience received: 0 percent, and it depends on your character level.
• Blue: "You may be unbeaten if you don't get absent minded." Trophy: possible. Experience received: 50 percent.
• Green: "Weak companion but don't get absent minded." Trophy: possible. Experience received: 75 percent.
• Yellow: "Be strained, it's same level as your level." Trophy: possible. Experience received: 100 percent.
• Orange: "It's stronger than you but you may win with your skills and strategy." Trophy: possible. Experience received: 125 percent.
• Red: "It's more powerful and don't think about to challenge it." Trophy: possible. Experience received: 150 percent.
• Purple: "It's absolutely stronger than you." Trophy: possible. Experience received: 200 percent.

The experience percentages come from the English publisher page. The Korean official page lists the same seven colors with descriptions and a trophy column, but no percentages.

Where the two pages disagree

The Korean official page marks the trophy column as 불가 (impossible) for grey and for purple, and as 가능 (possible) for blue, green, yellow, orange and red.

• Grey, 회색: "상대할 가치가 없습니다" (not worth facing). Trophy: impossible. Experience difference: varies with your character level, with a table below the color list.
• Purple, 보라색: "당신보다 절대적으로 강력한 상대입니다" (absolutely stronger than you). Trophy: impossible.
• Blue through red: trophy possible on both pages.

So a purple monster gives 200 percent experience on the English publisher page and no trophy on the Korean page. Both readings are worth keeping in mind, because the Korean page is the operator's own system page while the English page is the publisher's translation.

The level difference tables

Both pages publish the experience you get per level difference as images, one for a monster below your level and one for a monster above it. Both name the two images colorname_img01.jpg and colorname_img02.jpg. If you need the exact number for a specific gap, open the page and read the table for your direction rather than guessing from the color alone.
